PARENT FEEDBACK c/o Aman Kumar Shrivastava C/o ABHYAS Academy
10th
Abhyas institute is one of the best coaching institute in the vicinity of Ambala Cantt area. The teachers of the institute are well experienced and very helpful in solving the problems of the students.The good thing of the institute is that it is providing extra classes for the students who are weak or the students who miss the regular classes.This is also major advantage of institute.My experience in respect of Abhyas is very good as my children are gaining good quality education
