Limited my solving initially in 11th. I was in a lower batch owing to misunderstanding and the class environment and teachers were not very bothered.
My Maths teacher aske to do only RD sharma which I did indeed behaving like a noob. Did only HCV for physics.
Chem went fine.
Practice as much as possible in the initial phase.
I am yet halfway through recovering.
So the crux is practice as much and possible and do only quality material, once basics are good.
