Learn biology from the bio enthusiasts. I have 5 yrs experience in teaching all the branches of biology.

My brother is one of her student. She teaches not for money as most of us do now-a-days. She teaches because she loves the teaching profession. She explains most of the topic using diagrams. She goes in depth of every topic and try to make the topic easier as much as possible for the students. She loves biology (I know this because I know her from college days). She chose the subject because she loves it and wanted to excel in it , not because she doesn't had other options or family pressure
at that time like most of us had/have. Last but not the least you can trust her as your teacher and as a person too.
