Guys please save me , god please help me i am completely fucked.

I’ve been studying physics continuously since yesterday, only taking breaks for sleep, and I’ve managed to cover just five chapters. I still have a lot left to complete, and I’m really worried because I got 45/100 in my pre-boards. If I don’t score well in science, I won’t be able to take the science stream in the future, but I really want to prepare for JEE.

My biggest struggle is chemistry—I understand the concepts, but I just can’t seem to memorize equations no matter how hard I try, and I only have about 1.5 days left. I’m feeling extremely overwhelmed and don’t know what to do. Any advice would be really appreciated.

PS: I AM THINKING OF KMS IF I DONT GET GOOD MARKS!
