Final Exams: 2nd Semester (University)

My exams began on the 21st of December and ended on the 26th, a day after Christmas. For Christmas, I received a little stand-up makeup mirror, with a little container as its base to to place a tiny number of makeup items. I don’t have a lot, so I filled it with just my 3 nail polishes that each cost only about RM5 from Shopee, and a few of my mom’s lipsticks she gave me. I am quite a simple person; little things like these are enough to make me happy.

The edges of the mirror even has a light. You just touch the mirror itself and the edges light up! Cool.

On the 21st of December I sat for Math. My math is a little weak, and I did not really like the chapters we were studying for math in the 2nd semester (we study different chapters of math in all the 3 semesters), so I’m not sure how I did. I had reviewed all my lectures, but not done enough tutorials and did not do any past years, so I must admit that I did not practice enough. I have resolved to do much more practice for the math course in my 3rd semester. There were quite a few questions that I did not know how to do, so I definitely did not do as well as the other courses. (At university, we do not call subjects as “subjects” but rather “courses”. This is because three courses, such as Math I, Math II and Math III are all under the Math subject, but are separate courses).

On the 22nd of December, I sat for Communication Skills. I watched some debates on Youtube, and a video with very simple English on conversations at a workplace, just to get my mind set for writing dialogues. Eventually, though, I did not write a dialogue, I wrote 5 really short stories on cultural interactions, which was pretty fun, since I based many of it on my personal experiences. In the hours before my exam, I perused all m lecture notes at top speed and made handwritten summaries on them.

On the 24th of December, I sat for Inorganic Chemistry. Since it was an open book test, I made a handmade content page to make referring to my printed lecture notes easier. I had gone through most of the lecture notes in the week before the exam. Since there was a one day break between communication skills and chemistry, I used it to read all of my tutorial answers and a past year paper that our lecturer mentioned would be similar to our final assessment this semester. For Chemistry, all answers must be handwritten, so everything was rather rushed, but I still completed everything in record time and I believe I did well.

On the 26th of December, a Saturday, I sat for my last paper, Modern Biology. Modern Biology is the most interesting course this semester. So far, all the biology exams at university, being completely open book, were the most enjoyable for me because I get the joy of learning while sitting for an exam. I can search the Internet for a better answer, to complement my knowledge from our lecture notes. (Since all our courses have to have open book exams, the examiners have increased the difficulty of the questions, making them much more indirect and requiring much more thought. Yet with the Internet, my lecture notes, my tutorials and past years all next to me as I do my exams is one of the most powerful and enriching exam experiences I’ve ever had. It is, really, a food for thought on how we structure our exams in the future, even when the COVID crisis is over.) For Modern Biology, I reviewed my tutorial videos. I also made a summary on what we’d learnt for all the topics, and it made for great reference during my exam.

Then, phew! It’s time to relax! “You have to study soon, you know,” said my father immediately after my exam, pouring cold water all over my head. Oh well. But I still get to relax for a while first. Haha!

My results will be out in a 1-2 weeks. I do hope I did well! Then comes a hectic 3rd semester…. I am ready for the challenge.

3rd Semester for Foundation Year at university: Exams, Commitments and Opportunities

Having completing my exam, I am having my three week semester break now. One week has nearly passed already. It hasn’t been a very busy 2nd semester, at least not relatively as compared to the previous and coming semester. This is because I took only four courses in my 2nd semester, while for the 1st and 3rd sem I am taking 5 courses. It is fixed by my University, for foundation in science Health Science Stream students.

On top of that, I have signed up to take my MUET exam (an English Language Proficiency Test) which I must score at least a BAND 4 as a mandatory prerequisite to enter MBBS (medical course). I am also hoping to involve myself in some extracurricular activities, specifically helping the freshmen adjust to university life, and possibly taking potential students and their parents on some campus tours if we return to campus. One thing though – a few dates for training and bonding during the semester break have been set aside by our senior mentors, which I am still not sure I can commit to. It has been on my mind for a while, ever since I found that we will have training soon.

All these will fill my 3rd semester with the most commitment required so far, but I know medicine is going to be tougher. So the effort doesn’t daunt me. It is my father that may get in my way of participating in these co-curricular activities. Yes, even if these activities are all online, due to the COVID situation and rising cases. I have yet to break it to him, these activities. But these are things I want to and feel like I can contribute to. I am also hoping that these opportunities will open my eyes to interesting things.

My exam results may come out in a week or two, and so will our universities announcement on their decision regarding our academic study mode (physical, mixed or online). I will update you guys again when the time comes!

Watching from Malaysia: NASA’s OSIRIS-REx Spacecraft First Attempt to Capture a Sample of Asteroid Bennu

“We just want to jump up and shake hands and hug right now!” exclaimed Michelle Thaller, an astrophysicist from NASA Goddard’s Spaceflight Centre. “But with COVID-19, we’ve got to stay apart and protect each other.”

Defining moment in NASA’s history:
OSIRIX-REx Spacecraft touchdown – first attempt to capture a sample of Asteroid Bennu, and bring it back to Earth by 2023

“Touchdown declared.”

Sampling is in progress.”

At 6.11am, Malaysia time, (6.11am EDT time), I jumped up from bed and opened Youtube on my phone – just seconds after OSIRIS-REx’s first sample collection attempt from the surface of Asteroid Bennu 200 miles away from Earth, known as Touch-And-Go on the agenda. 39,000 people were already watching the livestream. NASA’s TAG Team cheered after a successful historic first touchdown attempt to collect the largest asteroid sample since the Apollo era (that would be in the 1960s). The only extraterrestrial sample that could be larger than this would be samples collected from the Moon decades ago.

So close! NASA’s OSIRIS-REx preparing for touchdown

The exact mass of sample collected, though, would have to be measured using a special method.

The reason why I’m so excited about this moment is because Asteroid Bennu is an ancient boulder-filled terrain, about only as tall as the Empire State Building, scattered with rocks and dust which may help trace back to the birth and origin of the solar system. Carbon-based compounds were found all over the surface of the asteroid, and these samples may just contain the ingredients for life.

I cheered, watching NASA in the US on the other side of the planet, who were themselves keeping an eye on the data sent back from OSIRIS-REx, 200 miles away from Earth.

Missed most of the action! But after scrolling through the live chats of thousands of people around the world congratulating NASA, and rewinding the live stream, I realized all of the images were only simulations. “We are collecting tons of images right now”, said James Tralie, social medialist and producer at NASA Goddard’s Spaceflight Centre, “but we simply don’t have the data rate to get the images back in real time. So they are getting backed in the spacecraft’s memory and we’ll start looking at those tonight, and we’ll have them available for everybody tomorrow morning.”

I can’t wait to see those images!

On social media: thousands of people around the world supporting NASA’s historic attempt !

This actually isn’t the first asteroid sample to be brought back to Earth. According to National Geographic, Hayabusa, a spacecraft developed by the Japan Aerospace Exploration Agency, returned with the world’s first asteroid sample in 2010, and Hayabusa2 will drop its cargo—a capsule filled with several grams of the asteroid Ryugu on December 6 this year. But these Japanese missions picked up only small amounts of fine-grained material. Asteroid Bennu is designed to pick up up to 2 kilograms of material, although the exact amount of mass collected is yet to be measured (in a day or two’s time).

“We backed away successfully from the asteroid surface – the team is exuberant back there. Emotions are high, everybody is really proud, and.. we have some work to do,” said Dante Lauretta, professor at the University of Arizona and Principal Investigator of the OSIRIS-REx mission. We don’t yet know how much sample we have collected. The next thing that we’re going to be looking for is, once the spacecraft has cooled off – probably got pretty warm as it approached the asteroid surface – once it’s stabilized, it’s going to point toward the Earth and start bringing that data back. Those SamCam images are going to tell us a lot of information about how the events of today went.”

OSIRIS-REx’s Touch-And-Go (TAG) first sample collection attempted completed flawlessly!

According to the National Geographic, who posted just moments after the livestream ended, the mission was first proposed in 2004, but was only competitively selected for the third mission in New Frontiers Program in May 2011. OSIRIS-REx’s original leader, University of Arizona planetary scientist Mike Drake, died only months later due to liver failure. Drake’s deputy, University of Arizona planetary scientist Dante Lauretta, took on the role left by his mentor. The OSIRIS-REx mission has since been carried out in Drake’s memory.

I’ve been so excited for the latest space updates lately, with three new crew members boarding the international space station just last week on October 14, Wednesday, 1.45am EDT time (1.45pm Malaysia time).

Unfortunately, I’m an aspiring doctor, far from being close to such opportunities, haha! If you want to become an astronaut, astrophysicist or be involved in space agencies, an engineering degree would increase your chances to fulfill such dreams.

For now, I am eagerly waiting for the photos to finally be delivered to Earth tomorrow morning, in Malaysia time (or tonight in EDT time), and for OSIRIS-REx to finally return to Earth by the estimated date of 23 September 2023 !

Asteroid Bennu’s a small and spunky one, both posing a threat to Earth while seemingly carrying evidences of dried up rivers or long gone life as well. A great big congratulations and salute to NASA’s TAG team, who worked so hard to overcome the numerous challenges posed by Bennu’s small size, and boulder-filled surface! We probably know Bennu up and down now, seeing the unprecendented amount of calculating, regular correction and up-to-2-centimeters detailed mapping required.


Brief self-intro: I am a Malaysian university student and aspiring doctor, and I post about anything and everything that interests and enriches me and my audience.

Final Assessment: Semester 1 Results!

Guess what – I managed to do well for the first semester! 😀

Those too simple, too brief alphabets you see under “Grades” is all there is to summarize all the hard work I put in for not just my exams, but all my other coursework throughout the semester.

My Final Assessment Grades
My Grade Point Average for the 1st semester of Foundation at university

The coursework I’m referring to includes two formal presentations, which took many nights of toiling and video-chat discussion with my assignment coursemates (which I have promised you I would blog about soon), all the full lab reports, one biological drawing which took a whole day just to draw (I’ll attach a photo of the drawing below!), a research essay and a cited chemistry poster.

Alongside that of course, we had to handle the 1st round of tests, then the 2nd round of tests, then our final assessment. We took 5 courses in our first semester, which adds up to around 15 theory-based test papers, based on the breakdown I did for you.

On top of that, all the exam papers this round has been deliberately made far more challenging, due to the fact that exams are open-book (with information from our lecture notes and the internet at our fingertips) during the Covid-19 crisis.

The biology experimental design video presentation we worked on for days was converted to a total of only 5 effective marks. The biological drawing which took hours of concentration, which I will now attach below, is only 6 effective marks.

NO shading allowed. Dense regions can only be indicated with furious, agitated dotting 😛

My wrist hurt a lot after drawing this. Haha! But it’s still my masterpiece.

As you can see from the 2nd photo I attached at the top of the post, I got a overall Grade Point Average (GPA) of 3.8511. That is well above the requirement to get into a medical degree, which is a CGPA of 3.50. However, if you notice from the first photo, I obtained below average marks for Chemistry, a GPA of 3.33. This is because my better marks in the other courses pulled my overall grade up.

Now, for the 2nd semester (which has just begun!), I am resolved to work hard and smart to obtain a 4 flat (GPA of 4.0). Admittedly, I had my father’s help in the first semester as he guided me using the printed lecture notes. His insight and intelligent input are priceless and highly appreciated, however, I had only half the burden to carry back then, and perhaps the training for stamina was much alleviated. This semester, he has helped me get a head start as well, but only in Mathematics.

The truth will prevail now, if I truly can manage to take on the responsibility myself and be competent enough to study, and learn, intelligently.

This is because to do well in exams these days, diligence is not enough. You need brains, you need to be able to think out of the box, and not take too long to figure out the concepts. It is an undeniable fact that to be a doctor you cannot just be hardworking, you have to be able to think intelligently as well. Dumbness and slowness is not welcomed in the healthcare industry, especially during your medical training. Both of which, unfortunately, I have a bit of in my nature. It is difficult for me to rush things, or else I will not be able to reap information properly.

Now, I must get back to studying for Biology! This semester, our biology course is known as Modern Biology (as opposed to Fundamentals of Cell Biology in our first semester). I find Modern Biology quite exciting, as it dabbles in the absolute basics of molecular genetics and biotechnology, which is particularly relevant to the COVID-19 virus mutation, and a very contemporary topic.

I am struggling to understand it for now, but with my determination I will do my best to overcome it, and make learning it fun.

What it’s really like studying SCIENCE in my university!

“Let me tell you about the four main categories in science,” said our Biology lecturer, on our very first lecture of the semester in university. I could not see my coursemates, but I could feel everyone’s ears perk up. Whoever heard of four categories of science? We’ve only ever heard of three.

“First, math is the most fundamental,” she says. “Then what is the most basic science after that?” “Chemistry,” someone tried. “No, it’s physics,” said our teacher. True. I suspected that was why doctors are commonly physicians in the US, because the word physic originally referred to both the practice of medicine AND to natural science (Merriam-Webster, 2020). “Then the next would be, Chemistry, and then Biology,” she finished. “Then Physics is derived from Math, Chemistry is derived from Math AND Physics, and Biology has elements of all of the above.”

Wow.

One thing I have discovered as in the first few weeks of studying foundation in science at university is: every one of these scientific categories has elements of another category. Math is most fundamental, and therefore only seems to relate to nothing, when you study it on its own. But when you get to the “more derived” subjects, you will see all the interconnected relations between the sciences: there is differentiation (math) in Physics, there are complicated molecular structure of chemical compounds (chemistry) in Biology, and there are logarithms (math), gas laws (physics) and enzymatic graphs (Biology) in Chemistry.

It truly is really interesting, when you see the bigger picture come together. You see the purpose of why things happen; why you are studying math when it seems to be just about numbers. Seeing the patterns and interconnections gave me a new insight into the subjects we had been studying ever since high school; and I wondered why we weren’t exposed to this earlier.

But here’s the really cool thing. I am not sure about other universities. Personally, I am certain not many universities must have this weird concept in their foundation in science syllabus: in our recent Physics exam just two days ago, a white blood cell and a Bacteria (Biology) are racing toward Point A at the speed of 20μm/s and 50μm/s respectively. Calculate the relative velocity of WBC to the liquid…. I laughed, as I read through the question on my digital exam paper, in my room. Maybe exams and studies have dulled the minds of people, and they don’t play as much as I do, and they might find me too peculiar for their tastes. But little things make me laugh, and that does not compromise my intelligence. I think that was a very lighthearted element to include in an exam, a strange rojak, as we like to say here in Malaysia (rojak = a mixture of random foods, used to mean a mixture of random things / languages spoken together, etc).

It’s cool.

Many of my lecturers are really good teachers. They bring across the topic to us clearly, they are prepared for what we might not understand, possibly due to their years of experience, or credentials in the field. They teach us the why of things, which is the whole point of studying science, and a great way to pique our interest.

I am really grateful for the opportunity to study foundation in science at my university. It gives me a fresh insight into science. Although I have been more of a quiet person in my primary and secondary school years, I hope to grab this last stage of education – tertiary education – with both hands, and learn and discover as much as I possibly can.
