sad he ain't here anymore cause he was really helpfull
Mr Tan was awesome!!! He's the only science teacher I've ever had that I did well on the exam. He provides you with notes to copy down (which are really helpful for things) and describes things really well. I know a lot of people can't understand him but to me he was really easy to understand. Great science teacher!
Good teacher although a bit hard to understand and picks on people in class (though it's pretty funny if it's not you).
Richard Tan is the epitome of politesse. He is truly a role model for every teacher. The clear way that he explains things is a great help to everyone, and he is very understanding of mistakes.
