I am Sethmika Hemachandra. In 2023, I completed my A/Ls and secured the Colombo district 9th position (Island 47th) in the Biology Stream and now I'm studying as a medical student in the University of Colombo. As a student, I've noticed that A/L Biology is a subject disliked by most students, myself included at the beginning. This is because it's often taught in a way that requires a large amount of fact memorizing. However, as I learned more about the subject, I came to see what an amazing subject it truly is. That's why I decided to pursue teaching Biology - to help students learn, understand, and enjoy the subject as I did.
