He's a really nice guy, but the notes he gives you are often a bit off track. Make sure always to check and study the textbook before tests, because that's where is tests are based from.

Mr.T's tests are super difficult, there are ap bio questions used, otherwise the class is rarely boring. Labs are usually interesting, and he is a very nice man.

he actually tries to teach students the material, and takes time to explain things, unlike many other bio and AP bio teachers.

I heard that he isn't that clear of a biology teacher. He is however a really cool guy that you can go to with your problems. We have fun and do nothing during study session. He's nice, just study!
