Let's figure the numbers easily, not being overconfident...
I can give 1 hour of demo class initially, for you to decide whether you want to attend my class or not...

I can explain math chapters from grade 8, with logics, and simple techniques...

What I need from your end it, little concentration...

I can teach math. Being taught doesn't help you in one-way. You need to understand, put forth the doubts, clear your mind, revise it in your free time, get back to me on the same topic if you need the explanation in detail or for the second time...

Mathematics is a subject, which is just an easy page to solve, only if we love numbers...

Being a tutor, I can help you in guiding with the subject to learn and solve. Rest has to be your effort. Concentrate, learn and revise, earn good scores in the school. 

Finally, I am just a tutor, you should be the one to achieve...

All the best...
