Hello Aarthy,

Both Allen and Aakash are institutes with very good success rates, but Allen has a slightly better success rate than Aakash. Both Aakash and allen have good study materials and exam systems. Some extra points of allen are-

1. It holds everyday evening doubt counters where many teachers are available for every subject.

2. They conduct Open session in which Directors and HODs interact with students and motivates them. The toppers of the periodic tests are awarded 'Saraswati Silver Medal'.

3. They have mentors who will help you to overcome any kind of problems as a student.

The main effort has to be given by you since 90% of the result depends on the student.

All the Best!
