For poly student to go into local university, usually the standard GPA is 3.5 point, although it depend on the course you want to study and there might be other factors they might look into.
Beside you will eventually be going to the workforce after your university, you might as well enjoyed your study in poly while you can instead of worry you might lose out if you take long route. Trust me, once you are in working life, you will missed the school life a long, like buddy friends (or true friends) and fun actvities etc which I hoped your future company might provide!
No , you can still go JC. I had a senior was very strong in sciences and math , but not gd in language. He got E for GP and hes in Bioengineering NUS
Go ahead and apply to poly if you're sure there's a course which fits your intended career. But don't go to poly just because you hate GP.
Being great in your English helps GP, but GP isn't English, and there are many students every year who are still not great in their English, eg. China nationals, but because they have figured out the requirements of GP, they still manage to score As and Bs.
Worst case scenario, you just only need to pass GP (quite easily done, as opposed to scoring A), and excellent grades in all your H2s will still allow you to enter many good NUS, NTU and SMU courses.
You don't need to be great in English to score in GP, like what UltimaOnline has mentioned
i attended a pre-u center during my time, i got B4 for GP.
i resit for the exam and got A2 for GP. later i did a Law degree with UOL as an external student, i got a Law Degree but not so good.
i sincerely think you can over-come your diificulty in english. GP is about critical thinking. I hope you can take the challenge.
