Update 2024-09-09: If you know me then you know what happened and why this post is kind of ironic.
CORRECT ME IF THERE IS ANY MISTAKE
NONE OF THIS IS CONFIRMED, I WILL NOT TAKE RESPONSIBILITY FOR MESSING UP YOUR LIFE
Theory
CUHK Science sounds very multiverse right OOOHH SCIENCE, but it is quite easy to get into even with trash grades. Refer to the image below:
Application
Take DSE 1 year early in Form 5, achieve those grades, if you are not confident in English, you don’t need 5, 4 is also fine. Put emphasis on m2 5* if you want to do maths since it gets you into the honours maths courses. If you do other science, increase your grade on that elective and m2 5* is optional.
Congratulations, you have just skipped the grueling period of your life called Form 6 (although your form 5 may be a bit busy). Have a good time in CUHK!
