I am an Excel Expert, I can teach you Advanced Excel and data analysis with Excel.

I studied mathematics from him and he teaches maths very good, he goes deep down to the topic and he has his own style of teaching the subject, like he breaks a complex topic in such a simple way that even if you do not know anything about the topic and even if topic seems very hard to understand, you will learn that very simply. Like you will find that you knew that topic for years. so, yes his way of teaching is very unique. That's what I liked about him.
