STUDENT FEEDBACK - Upmanyu Sharma C/o ABHYAS Academy
 7th
My experience with Abhyas Academy has been very good. When I was not in Abhyas whenever teacher ask questions I could not speak it confidently but when I came in Abhyas, my speaking skills developed and now I am the first one to give the answer of teachers question.
