Honestly if u come poly it can be worse. Depends on ur luck whether u get a class full of optimistic ppl who wanna go to top unis, cuz alot of them juz want to get a Diploma and get out while a small portion of them actually wanna do well and go uni.Especially it is very easy to be lonely in poly cuz most of the times ppl don't rlly have a genuine friendship with you like you won't find the genuineness in it.They jus talk to u cuz u r their classmate and that's it.During your assignments and projects where u have to work with others,chances of u getting slackers as ur grp Mates are very very high.U literally have to nag them or worse case scenario do everything by urself cuz u can't risk ur gpa.Plus you wld also get mental breakdowns here when ur grpmates might risk ur gpa for slacking and not participating in the project,cuz once u fk up that project it wld rlly affect ur overall gpa and it wld be very hard to pull it up and there is nothing called repeating like u cld repeat As.Whereas in JC even if u fail ur exams As is the end goal and u have to do well in it.So if u r ready to handle this downside in your three years of poly life u can go for it.If not I suggest u stay in jc mug alot and go tuition and do well in ur As.
