see ...  be it any exam.....aieee or any other ...

you need to prepare really well....and so it is up to you to decide how many hours to study.....

but complete the topics that you have planned for the day........it may take less time or more time than what you might have planned..

but you need to complete that particular topic......and that too with perfection.

whatever time you allot , make sure you  follow and complete that...

 

Plan out your work and work out your plan ....is what i have to say...

 

you just need to know basic english in order to understand the questions.....

 

all the best...!!!
