Only best friend can understand thair friends problem. and I think "" Ravindra Rathod"" understand our problem and find a solution on one of common question of student how to study? And my friend write a book ""gyan sutra: padhai ke"" sikho, kaise sikhe? Wonderful! How to study? It is very common problem but it's iffect is very deep. if we know how to study proper we can learn any difficult subject also. Ravindra Rathod did a successful job. Written a beautiful book ever I seen. When I was read this book my cenario to seeing study is get changed in complately positive. In this book all information about study how manage time? How set goal? How smart read, write, remember. All small aspects of study represent very deeply . Sayyad Samir ( upsc aspirant)
