Abbott was a great science teacher for me. He was super nice, super helpful, very good at explaining stuff, and was very reasonable about homework as well as potentially rewriting tests. All in all he was a great teacher. I would advise for you to do all of the homework though. I remember when I was in his class he wouldn't dock marks for not doing homework, but he would keep track of whether you did it or not, so if you don't do well on the test for that unit, then he know that you didn't even make an effort. He's a great teacher and his class is a great experience
