#### Boubacar Siddy Diallo

##### Mathematics Tutor

Is Math frustrating? Have you been told that you don't have a Math brain? Do you understand Math, then forget?

A year ago, I identified the reasons why students struggle with learning Mathematics and came up with solutions. I apply those solutions when tutoring students. One of my students changed his major to Mathematics and currently work as a Math Tutor at a college. I will show you the same learning strategies in this course and I am confident that you will do well.

Let me help you learn Algebra.

The instructor Mr. Boubacar could have given a fair introduction on the subject with a reference book besides improvise and make it digitalized or a best style handwriting. This course is a great start for the elementary level Mathematics students in Algebra. Thank you so much. God bless you, Sir.

An easy refresher on what I learned from my previous year in school. He has a few interesting and new methods that I haven't seen before.
