Kitne log hai bhai yaha ranchi se
@sonu_shaw yes, solve the dpas. Mostly they are good. Toppers in lalpur centre solve almost every dpp. It's true there are some mistakes sometimes but they are noticable or can be verified by teachers.
Nobody will mention to you about dpa bro. The hard workers solve them silently and ask doubts. Whenever you go to fiitjee, you will see teachers are never free, always someone will be there asking doubts.
Although i would add that it's not like it is necessary to solve the dpas. Solve them if you like for extra practice. They have a collection of questions gathered from various books.You will also get cpps which the particular teacher makes himself.
