How to become a pro at Biology within a short span of time

Yamini - is the most effective, skilled, creative teacher I've come across! She has her way to explaining things to a student which makes an effortless experience to understand things. I personally suggest Yamini as a bio teacher since she's very knowledgeable and makes it worth the time. She's never says no to learning new things and makes it very interesting for the other to learn as well. It was a bliss to learn things from Yamini! :)
