A lot of my friends have studied at aakash.It is one of the most prestigious institutes when it comes to engineering and medical preparation.All the faculties are highly qualified and trained.They are highly supportive .The institute provides experts for every chapter they teach which is very helpful as even the most average student can get to the core of the topic.
However the results that they publish are not always true.The routine that they follow is however not liked by the student as per my friends knowledge.But still they charge a lot of money so they should decrease their fee structure.
