I'm poovizhi Kathiravan international student pursuing masters in biomaterials at university of Manchester. Basically I believe each and every student will find a subject or a lesson difficult when they can't understand the core I will explain clearly and may take time until I make sure the student understands the concept in a simple manner. With the easy examples they won't forget. And then I will teach them the difficult ones by step by step so they won't forget it and will understand then read. I will evaluate them once in a while to know where they are finding it difficult and will concentrate on those a little more. I will engage them during the class without making them bored and hate the lessons. And if possible I can give them some science based activities to make sure they have a partial knowledge on those concepts they have learned and will teach them to use those in their daily basis.
