STARS Secret Manual.

Learnings from both semesters has given me terrible course for concern. I suppose this must be posted for the welfare of succeeding generations to come.

For first semester:
Fastest Fingers first. Ignore those waitlisted crap, nothing of your concern. Just wait, choose your UE and GE nicely, keeping clicking 'Add course into STARS' in STARS Planner one minute before Registration Time. Once the window opens, quickly confirm and you're in.

For second semester:
1st Registration Period -
Gun for your PE only. That's the only fastest fingers first. Keep clicking as above, and confirm quickly. Ignore the UE priority crap, focus on clicking confirm!
Choose GE that has a reasonable vacancy-waitlist ratio. (ie. if the course has 0 vacancies and 100-over waitlist, you're not likely to get it)

2nd Registration Period -
Choosing UE this time round. Repeat as per GE-choosing.

Some tips:
1. Add/drop camping does wonders sometimes.
2. Sit on top of modules. You can drop later. Not ethical or nice but a lot of people do it to save their own skin and cover their asses.
3. Registering at school is quicker.
4. Waitlisted modules can clash with each other, but not with GEs and PEs that are set in stone.
5. The higher the waitlist, the easier the module is. (Generally)

Shall update this when I learn more!
