Dear Sir Thusitha,
As I come to the end of my A2 journey, I couldn't leave without expressing how grateful I am to have learned biology under your guidance, Sir.
After studying AS with you, choosing to continue A2 with you was one of the easiest and best decisions I made. The clarity you bring to every lesson and the way you make even complex concepts feel simple is
something I truly admire.
What amazes me most is how effortlessly you teach, Sir. Your ability to recall and structure content entirely from memory reflects your deep understanding of the subject, and it shows in every explanation. It's truly inspiring to learn from someone who teaches with such precision and
passion.
I also really appreciate how you guide us to answer questions exactly as examiners expect. You've not only taught us content, but also how to think, approach questions, and present answers effectively, which has made a huge difference, Sir.
I've said this before, and I genuinely mean it, Sir, you are one of the best teachers I have ever come across. I feel incredibly fortunate to have learned from you during such an important phase of my studies. Thank you for everything you've taught me, and for the impact you've had on my learning journey.
I'll carry it with me long after these classes come to an end
with sincere gratitude,

"I had the privilege of studying Biology under  Thusitha sir, and his teaching played a major role in my academic success. His lessons are well-structured, easy to understand, and focused on both theory and examination techniques. He has an exceptional ability to explain complex biological concepts in a simple and engaging manner.

The regular past paper discussions, personalized guidance, and continuous encouragement helped me build confidence and improve my results significantly. His dedication to students and passion for teaching make him one of the best Biology tutors I have ever encountered.

​I am Sarindu Samarasuriya and I was a private candidate for Pearson international advanced level and I was fortunate enough to contact Dr.Thusitha , since day one I started for studying to this exam. Dr. Thusitha is one of the most amazing teachers I have ever met in my life his teaching pattern is so simple, very efficient and productive for a subject like biology. Thanks to his tutoring I was able to complete Pearson Edexcel Biology syllabus in less than 3 months and get an A*.He has helped me both during the sessions and after the sessions regarding subject matters and I can guarantee that he will try his absolute best and dedicate his precious time for the betterment of his students. I’m truly delighted to be a student of him.
