Honestly my chemistry understanding went from bare minimum to a very deep level . Sir explained every topic with at most dept and interest . I have gained a lot of confidence in my performance over a course of just 2 months . I qualified neet with my score booster to be chemistry. I improved from around 50 ,60 in practice tests to 130 . He would give me many practice papers and his own online video lecture with which I improved my understanding at a more fundamental level . I can say one thing for sure , if you take sir 's classes or help, you are destined to improve chemistry and it will become your favorite subject. I got his contact through a senior who also qualified neet .
