Difficult Math made Manageable for grades 10 , 9 and 8

I hold a Bachelors degree majoring in Math and Stats from the prestigious St. Xavier's college and having taught Math for close to 20 years , you will start finding the subject much relaxing and refreshing if taught my myself and that will boost up your score in the school exams. I have my own YouTube channel which I cannot make a mention of on this platform , however , the thousands of positive comments on my YouTube channel depict my natural and God-Gifted teaching skills.
