I've been tutoring online and in person for some time now. Being a good student, I've always been one to help my fellow students with their doubts and help them understand new topics well. I have often helped my peers with problems they've been stuck on, and also tutored younger students in my neighbourhood often. I find it really helpful to continue learning, and that helps me to redo stuff to help others in their learning. I think that I can be helpful to anyone who needs to get rid of certain doubts, and I can also explain topics with good efficiency.
