Hello, 

This answer will vary from person to person because this is so personal question. You cannot compare such classes that easily. I'll initially say ask yourself how strong are you to go for a drop. How's the Josh in you? If you are dedicated enough, any of the above classes will help you go well. Just be punctual and don't repeat the mistakes that you did this year. And study hard and be regular with ur classes. Now coming back to your question, I'll prefer Allen Kota to be a good class as they make you sit to study for long hours there. They cover the whole portion well and teach you every thing from basics. 

The choice is upto you now. 

Best wishes.

Thankyou.  

Hello dear student, I have experienced both of these institutions. I have studied 2 years in Aakash and one year in Allen Kota while I was preparing for medicine. So I would suggest you out of how I feel personally about both of them .so I would suggest you to go for Allen Kota but do study like anything as you will be living in hostel or Pg whatever suits you . There you would be having only 2 things to do study , sleep and food. Avoid taking smart phone there because it's a huge distraction and people usually don't study and divert their minds. Rest Aakash is good too but nobody can match the level of Allen Kota . This is my personal recommendation. There you give tests every week although it's there in Aakash too. But teachers in Kota make you study like anything and I personally feel it's the best. .. hope this helps.

Best wishes
