Hello student,

Assuming that you are dropping your year for preparation of any certain competitive exam. Then the course of 1 year is quite sufficient for droppers as you already have the basic knowledge of the core subjects and there's nothing new to study. Just the thing is that you have to learn and understand things in a precised manner and you have to increase the level of your mind so that you can answer the questions which is being asked. Be focused. The course with 1 year duration is better option than 2 year duration.

All tbe best!
