Doesn't make you work hard enough - fill in the blank notes! - no homework. Doesn't give good feedback so that you know what you are doing wrong. He's a really nice guy but his lectures could be clearer and the class could be tougher.

Kraii is one of the most effective professors I have had in my college experience. He has a great understanding not only of biology, but of life as well. He's makes great connections between all disciplines, and is available 24/7 despite his job as a vet. Careful, you might end up a bio major!

I found his teaching style to be very confusing. He is definitely one for going off on an irrelevant tangent (usually about go greenno frackhate gizmosfair-trade coffee).

Professor Kraai is really passionate about teaching and gives help when you need it. While he does talk a lot of politics in class, most of the material on the tests is in the notes or relates to something the class goes over in lab. You really do have to study the material if you want to get a good grade though.

Dr. Kraai is a fantastic professor. He expects a lot from his students and his class was practically a full time job. BUT, I sincerely learned more from him than any professor I have ever had. The exams are in depth but almost exactly off of the pre-exam quizzes. If you go to class and work hard, you'll do well and learn more than you'll expect.

He gives you study sheets before the tests and lab practicals (PLURAL)... but he still puts stuff on the tests that he never covers. He doesn't believe in people getting A's... he only gives A- or below. He is extremely liberal. One good thing is you don't have to buy a lab manual.

Most people dropped the class already. I spent probably 90% of my free time studying and ended up failing. His notes are extremely disorganized. The study guide is all over the place. He uses abbreviations for everything and expects you to know what they are immediately. Admited he purposely makes tricky questions which fails people. STAY AWAY!

Worst professor I have ever had in my entire college career. Stay completely away. Study guides don't help even when you study and know them word for word. Goes out of his way to make simple concepts difficult. Heavy on T/F questions and lets you know that he makes them hard on purpose. Not sure why he tries to make this the most difficult class.

His tests are not based on actual lecture/course material, rather his own opinions/interpretations of it. His T/F questions are just weird. There's a reason most of his ratings are bad. He rambles during lectures/labs and returns back to the original topic when it is almost over. He's a bad professor.

Biology isn't difficult at all, he just makes it much harder than it should be.

WORST PROFESSOR EVER. Do not take this professor if you have a life outside this class. You will be spending all your free time studying just to try to pass one of his exams. This guy does not deserve to be teaching anyone. This was the hardest class I have ever taken and I have already taken A and P. Stay far away from him.

I didn't have great experiences in the geology OR chemistry department at OCC. Professor Kraai puts excellent time and care into his work. He is old school and hand-writes his notes, but this class is worth your time and effort. It is a very tough class, but only because he is so knowledgeable in veterinary work, biology, and sustainability. 10/10

Anyone who rates Kraai on the lower side is just reflecting their level of participation and responsibility for the class. Whatever effort you put in this class is surely reflected in your grade, as it's mostly all about how well you note-take. He is humorous in a way I think people confuse for malice.

His assessments are based on his perceptions of the topic rather than the actual lectures or course materials. His T/F inquiries are plain strange. There is a cause behind the majority of his poor evaluations.

He honestly makes me hate BIO & it's my major. Absolutely horrible, avoid at all costs. Page should be the only teaching GEN BIO. Extremely heavy on True & False& they are not relevant. He's very disorganized & his notes are worthless. I had him for 151 & then again for 152 because there were no other sections. His class is a walking nightmare.

He really makes me despise biology, which is my major. terrible, stay away at all costs. Very heavy on True and False, and they don't matter. He is completely unorganized, and his notes are useless. Because there were no other sections, I had him for sections 151 and 152. This was horrible.

This class is pretty difficult, but I found it really enjoyable! Beware, the professor has a dry sense of humor that you may interpret as him being rude, but he's really trying to joke around. Lectures can get pretty boring and he's a tough grader, but you can tell he's very passionate about biology and extremely knowledgeable!

Two years late to this, but I have to say that class with Peter Kraai made me lose my love for science. Even with amazing professors following him, I still ended up switching majors and schools altogether solely from the horrible experience. I don't know if he still teaches, but if he does, run the other way and don't look back!
