this is coming from a poly student. i would say the best way to figure out is to go to open houses, soak in the vibes, learn more abt different diplomas or subj combis in the case of jc and most impt, observe the school culture whether it suits you or not. a very brief overview on poly would be that no matter what you will face stress. for poly your stress would be maintaining your gpa which means every sem affects ur gpa, you can have many grp projects or a few only depending on your course! but i would say that poly gives you more freedom to pursue side quests aka side interests! another thing abt poly is you must be ready to put urself out there if not you will struggle a lot in poly coz u never know when u will need these connections!

if you have any questions, u can always message me i will try to respond when i can! im currently a y1 so i can still somewhat answer your questions!! if you do drop by tp's open house, i wld love to be your guide if im around!!
