I love to give first hint or idea of solution so that if possible student can work on it to learn something from it. If student unable to solve it then I will give intuitive idea about problem or topic and make sure he/she understand the concept very well. Currently I am teaching assistant in one of best Science institute of India named as "IISER Pune". I hope that student love my teaching process and learn lot of things from me.
