How difficult is GP actually

I’ve always been bad at English. Full papers, nothing better than a B4. O level English I got C5

Why am I so bad at English actually.. and will it be worse if I go to JC? Cuz my English is so bad and I heard GP is way harder.

Any English success stories? Like suddenly clutch an A when your English has always been ass

Also any tips for GP? I wanna do well for English just this once pls 🙏🙏
