I'm a student studying M.B.B.S presently and I have tutoring experience of about 2years . I'm in my learning phase but I love to share my knowledge . I feel satisfied if I can help someone with the knowledge I have . I'm a medical student right now and in future I will be doctor and treat patients . Tutoring students makes me feel that I will be able to help people the same way I help students. Tutoring helps keep the knowledge in brain fresh and I think will have great experience in SolutionInn helping students .
