He is easier to learn from than Bundy. I dropped Bundy and took Hens. I understand him better, but I'm not a Bio person at all. He makes pretty good analogies and tries very hard to help his students. He gives curves because Bio pass rates tend to be low. Do the Bioportal assignments; they help. Do iClicker stuff in class as well; he'll give points

Overall, his notes were not organized. You start talking about one thing then jump to another... then you come back to the first thing again much later... Tests are difficult, he often puts either two "right" answers (you have to choose the most correct of the two) or partially right answers that are almost identical to the correct one.

Don't get me wrong, Dr. Hens knows his material, but his tests are practically impossible to pass. I spent countless nights studying for his tests and I still receive D's. I go to SIP and look over the CLO's he's posted and to no prevail, I still manage to fail his tests. If you think you did well, kill that thought.

He sometimes goes in depth about topics you don't need to know much about, but it's only because he's passionate about what he teaches. His lectures are actually enjoyable and he gives extra points on tests sometimes. If you take his class, my advice would be to use the textbook to answer CLOs, attend SIP, and study and you'll do fine.

Would not take any of his labs again. He does not give you feedback on any of the lab question until the end of the semester when grades are do, so if you have incorrect lab questions you are unknowingly putting them into your end of the semester lab report. Also does not respond to any of your emails, but over nice guy in person.

It was a good intro. BIO class. The class was enjoyable and the lectures were always great. Dr. Hens knows what he's teaching, and he always looks for the best examples so students can remember the material. Go to SIP and print/answer the CLO's he posts. I would highly recommend taking his class.

I was not a fan of biology until I took Dr. Hens' class! Lectures were interesting and fast paced, most importantly, EXTREMELY important for tests. However, the most important are the CLOs, they have everything you need to know. There's a lot of memorization. Dr. Hens is helpful and genuinely cares about his students and makes that very evident!

Dr. Hens is a very caring professor but he is not the most organized. You'll have to study based on the powerpoints and maybe read more detail in the book. Tests are like 66% and you have 3 of them + a final. Before every test there is a quiz. I recommend group studying!

I took Dr. Hens in his BIO111 class last semester. While he does know what he is talking about, he does come across as a bit callous when speaking to students. Lectures were a little boring but he does give you all the material you need to succeed. Quizzes and tests were extremely difficult - even though I studied it felt like it wasn't enough.

Cell biology is one of the hardest courses Ive had to take. A LOT of information is given in a small amount of time and almost immediately after completing, you have a quiz and exam. Time management is important and studying as you learn is best. Dr. Hens does listen to concerns and wants you to do well, despite the tests being very difficult.

As long as you look over the CLOs that he gives you, you'll get a guaranteed A on the tests. Just pay attention and if you miss class, go over PowerPoints.

I believe that if you receive subjects easily, this prof. is probably fine to take. However, given that most of your grade comes from the few tests given, you better do a good job every time. There is a lot of material to cover, and I'm not sure I'd take him again. Not a bad teacher, just packs as much material as he can each class; feels rushed.

Not sure why tests are worth 61% of the class but it puts a dent in your grade I'll say that lol.
