Hey everyone, this is Anaranyo Sarkar. Student of Kasturi Edu, in Class 11, the Wednesday batch. I just wanted to narrate my experience with this institution.In the fast-paced preparation for JEE, I have seen that it often happens that we are unable to fully be at mastery of a topic, or acquire a wholesome complete understanding of it. While it has happened many times that I have learnt many chapters in Physics and Chemistry with only enough depth for problem-solving. But thanks to Kalyan sir, Mathematics has been a whole different area for me. From just a subject in 10, to a literal source of enjoyment for me in 11, I owe this change to KR Sir. I am not ashamed to admit that I dont think I learnt REAL mathematics since I attended these classes. I couldnt be happier with what Kasturi Education provides for me. I recommend it for every serious JEE aspirant...you dont have to be an extraordinary student, its just the effort that is needed, and with the guidance you receive here, success is just the beginning of everything.

I would like to say that- just attend Sirs class and get to know about what actually the subject mathematics really is, along with the crystal clear concepts of each element of the subject discussed in class,problems of tough entrance exams will be simple if you follow him and do what he says...-Srijan Royclass XIMonday Batch-Kasturi EduationSession-2021-23

Even during the lock down due to COVID-19 he has put into effect a system where we students dont have any difficulty in following the class or asking our doubts-which he attends to for each and every student. He not only teaches us Maths as a subject but as a part of our everyday life and his lessons are lessons for life. I would suggest anyone aspiring to become an engineer to do so under the guidance of KR Sir and his brainchild Kasturi Education Pvt. Ltd. And the duration of the class? - no need to be concerned about that- KR Sir does a lot of hard work behind his students and puts many more hours than the normal class timings to guide his students to excellence.

I have been a student of Kasturi Education for my +2 level. KR Sirs brilliant and innovative techniques inculcated a deep love and passion for the subject that has stuck with me since now. Sirs methodologies and systematic approach to solving MCQs in a quick and logical manner helped me and many others clear one of the toughest Engineering examinations in this country. Not only his mathematical coaching, but his advice about life and career choices has been of immense help. He helped everyone in his class to success in either ways. He has been an inspirational mentor of my life. If anyone wants to excel in the field of Mathematics, joining this institute is the best option.

Every aspiring engineering student should join this institution.His unique way of teaching helps to build up the basics and eventually be also familarised with the tough questions of each and every chapter.

K.R Sir is the best mathematics teacher I have come across in my life. He can make any one love maths.

Simply the best institute for IITJEE Maths.
