Heyyy aspirant

According to me you should focus on all the easy concepts that you have your built on . Once you are thorough with those concepts then you should jump to those concepts that are lil tough and hard and you have practiced a lot earlier but you are not strong with them right now . You should try to solve all those questions which you have solved earlier.  DO NOT JUMP ON TO NEW QUESTIONS .

For the hard or lengthier concept you should try to solve more of the basics .

DO NOT INDULGE IN NEW CONCEPTS .

hope this helps .
