Dear aspirant,

Nowadays, big coaching institution have become business organisation whose sole and main goal is to earn maximum profit. I can't say much about coaching but you can get the best series of videos lectures on YouTube.

See, if you are self motivated and confident of reaching your goal, you can join any Cochng centre and prepare well. There is nothing in the brand it's the attitude of the students and the teacher which fetches you a good result.

One year courses in Aakash may fetch you a good marks and then may get you a good colleges but trying for first time for crash course I won't prefer because only few are benifited  so all the best .

Overall Aakash is good cochng. 

Hope the answer is helpful.
