Mr. Dempsey is an awesome teacher and a super chill guy. The tests are hard, and you should NOT procrastinate your outlines, but he grades the projects relatively easy and he lets you use your phone to do research and stuff in class. I definitely hope I get him in a few years for AP Bio!!

He's an absolutely amazing teacher and truly loves what he teaches. I took his summer bio class to prep for doubling up this year and I think he rocks. He's really patient, clear, and is always there to help.
I'm honestly really disappointed because schedules came out and I don't have him. Zut alors!

Very vague. Tends to spend the first 3/4 of class on the first three slides of the powerpoint and then rushes through the next five. When he answers questions, his answers are vague and not insightful. He loves those who always get As on tests.

I loved him in the beginning of the year. But as the year went on, I felt like he purposely picked out students who get bad grades and then intentionally calls on them during class to answer a question. I've been one of these people and not only is it humiliating when you don't know the answer, but he continually calls on you for the rest of the year more than he calls on other people and being called on and being embarrassed in class can really ruin the class for you.

He has good intentions. Wording on some questions is stupid though. You have to play lawyer to argue points back. Talks repeatedly about certain things (evolution, RNAi). Know those things and you'll do well.

Mr. Dempsey is an awesome teacher who supports all the science programs at school. Summer science research, science team, bio h and ap teacher. The powerpoints can get boring sometimes, but still somewhat helpful nonetheless. Homework is checked on the day of the test, so you can put off 2 weeks of homework into one day, but it's not exactly suggested. He gives his Honors students too much freedom and let's them interrupt him and move around and sometimes be obnoxious though.

Mr. Dempsey was a great science teacher who really wanted his students to do well. If you listen to his advice for tests and projects it is a lot easier to succeed. Also Mr. Dempsey is a really funny and overall nice guy. His class is a lot of fun with his biology jokes and his occasional picking on students.

Great teacher, and he knows a lot. The class isnt very hard as long as you study the ppts. Out of the three Bio H teachers, he is in the middle for grading and awkwardness. Matthews is the easiest grader and the funniest, but Hone is the toughest grader and he isnt as funny. Look forward to having Dempsey.

Very easy teacher if you are in his bio class. If you are in there you are obviously smart so you'll be able to manage anything he throws at you. He really doesnt care whatever you do as long as you are getting good grades as I was one my phone most of the class and he never told me to put it away considering I have a B+ average. He's pretty smart, but some of the conversations you have with him are very.... funny. Especially when you get to the reproductive system.

Picks favorites after the first test. If you get A's, he loves you, if not, he hates you and looks at you strangely. Not any easy class, and most of it is just studying on your own. Other than that, he's a nice guy.
