Welcome 👋

Hi! I’m Harvey Lim, a 3rd-year student at Aalto University. I also go by “rv” or “shzhe02” online.

Hope you find something interesting!

[5] Final Report - End of Exchange

This is going to be a really long, detailed report about my exchange semester at NUS. Some parts are just about administrative processes and paperwork, which may be boring, so feel free to skip and read as needed. I’m simply going into a lot of detail as I myself wished I had known everything about what to expect before my exchange. Also, get ready to remember a whole lot of abbreviations....

[4] If I were to do it all over again...

There were many things I wish I did differently for my exchange, so I’ve decided to break down everything I would do or wish I’d known if I were to do this all over again. Pre-departure Glossary: SEA: Southeast Asian EA: Eastern Asian AC: Air Conditioning OSE: Offsite Enrollment IPA: In-principle Approval NIR: National Immunisation Registry Course Selection Check NUSMods for course reviews by previous local students to get a grasp of what the courses are like....

[2] Initial UI Planning

Warning: I am not a UI/UX designer. I haven’t learnt anything formally, so my method of designing interfaces is essentially: Make sure I can figure out how to use it fairly intuitively Make it not look like an eyesore Design 0.1: Paper Sketch As I am not very familiar with design software, I decided to go with my most comfortable design medium: pen and paper. Here’s my initial design. (Pardon the illegible handwriting) I hope that got the message across....

[1] Goals

When I tried to use habit trackers, they actually worked for the first couple weeks. However, I soon noticed a few shortcomings with some habit trackers: Gamifying habit tracking doesn’t seem to work for me, as it abstracts away the actual habit a bit too far away. If my goal is to play a game, doing the habit itself feels like a chore. I want my habit tracker to be very in-touch with reality....

[3] Academic Matters

Course Selection At Aalto, our course selection process simply involves checking Sisu (our course management system) and registering for courses during their registration period. They rarely check for prerequisites, and it’s almost guaranteed to get any course you need. Registering for exercise sessions is done alongside the course registration; you simply select which exercise group you wish to be in as part of the course registration process. It sounds a little complicated, but in reality, it involves ticking a few checkboxes before hitting the “register” button....

[2] Post-arrival

Landing After landing in Singapore, I went to pick up my SIM card from one of Singtel’s pickup points. Upon picking up my SIM, the person working at the kiosk also offered to sell me a NETS card. Transport/General-use Prepaid Cards Singapore has a couple prepaid cards they use. These cards are usually used for public transport, but some of the types of cards can be used elsewhere for paying for other things....

[1] Pre-departure

Applying In January 2023, I applied to go on an exchange semester at the National University of Singapore (NUS) for spring of 2024. It was a all-in decision, as in that if I didn’t get the opportunity, I wouldn’t go on exchange at all. Luckily, my application was successful and I was nominated to go on the exchange by my home university, despite NUS being the second most applied to exchange destination at Aalto....
