Hi sparta . Well you have miles to go now as you just have cleared the cutoff but its not impossible just follow the steps completely by heart and i promise you will get below  10 k rank first coming to physics go through the hc verma only just the basics and even solve the solved example and no other book is required . Now coming to chemistry just go thoroughly through NCERT even for Physical , inorganic now for organic you can use himanshu pandey and for maths its all in you mind questions are easy go for cengage and just solve the questions till level 3 .

At last plzz be calm during your paper bcoz we messed up mostly during exam time .

I m sure you will do great
