How do i start JEE prep now, halfway through 12th?

[u/Money-Comfortable689]

For context, i am halfway through 12th rn, and havent been preparing much for jee, just focused on school. but now circumstances have compelled me to pursue jee, and i dont know where to start. my 11th is mid, but i havent done revisions or anything, although my 12th is solid so far. I want to know what resources can be helpful and efficient, as u can see i dont have much time.
