Hello Aspirant

If you want to do a crash course then I think going with AAKASH is a dicey decision. It is true that AAKASH is a good brand however there are many better and cheaper options like Careers360 courses for JEE. If you want to prepare for JEE Advanced then I would suggest to go with either Allen or FIITJEE.
