WTF DO I DO???

I used to study like around 6-8 hours a day normally till my second preboard ended. Since then I have not been able to study for even 3-4 hours properly. I have made like 2-3 timetable but could not follow any of them. Really need help.

This is the time when everybody locks in and thats the reason they get 90+ in boards but so low in preboards. The worst part is that i am not even feeling any stress regarding boards.

Give me motivation, tips or any such things. Looking at a few other posts and comments I realised that I am not the only one suffering from lack of motivation or lack of stress. If anybody has any way to solve this please help, motivation of any kind, anything.

AT THIS RATE I WILL BE COOKED ngl.
