I have working as a tutor in my student life for 4 years .I focus on basics and then try to make the mind set to solve the problem and create intrest of student in math. I believe that perfection in math subject comes by practice so that why i teach students one and and then ask them to do questions by your self if they cannot do it they need to think about it to creat a mind set and intrest in math. And they can see the solution just to verify there answers and to check the step or formula .
