4 flat? hard? You result sucks. Don't even think about 4 flat. haha
You need more motivation from others.
Then only can study hard from now.
Just like myself. I didn't study for my History for PMR till 1 month before exam cuz my friend had finished the whole book. I scored A because of him. He insulted me and kept showing off when he had well prepared.

Another case is to create more interest in the subject you like. I scored A1 in Physics in SPM because I started to love it at the last 3 months before exam. Form 4 and Form 5, I got 30-55% only. WHo knows actual exam A1. No joke.. put more effort.
