Hello 

Both AAKASH AND HELIX are good for preparation of NEET exam . you can choose any institute between them.

Now i'm gonna tell you about them in brief 

1. AAKASH 

They offers regular classroom programs , distance learning , E - learning programs. The courses are long term , short term, test series and crash courses.

2. HELIX

They offer correspondence course,crash course,test series , 2 year regular course.

They have only one branch and that is in Chandigarh.

Dear Abhishek,

I would recommend Aakash institute as it is a renowned institute for medical. They have good faculty. Helix inainstit management and technology is situated in Gurgaon. 

However, no matter which institute you choose if you don't study by yoursely then it will all go waste. Many students crack exam without any coaching. I would like to tell you that do more self study.

Regards
