I have been coming to Thusitha Sir's Biology class for six months. As a student I have learnt a lot from his tutoring. He makes the lessons more fascinating by comparing it with real life. His teaching methods are very practical.

Thusitha sir is a very determined sir. He has a huge knowledge on the subject matter in fact he is a scientist. His teaching is at the very top. He discusses the smallest point and explains everything in detail.

The Things My Students Say

BIOLOGY CLASS

Biology can be complicated, but it is also very interesting if you take a step back to think about what you’re studying. Having the right attitude can make it more fun to study. It will still be difficult, but if you’re interested in what you’re learning, it won’t feel like such a burden.It can be helpful to connect biological concepts to real-world situations.Think about how your body works. How do your muscles work together to allow you to move? How does your brain communicate with those muscles to tell your body to take a step? It’s very complex, but all of the cells in your body work together to keep you healthy.Biology teaches you all about these processes and how they work. That’s pretty fascinating if you think about it.
