He didn't include much information on his slides so you must take really good notes to do well, but for the most part he clearly explained all the topics.

John Orrock is the Man! he has the most interesting lectures and makes you want to attend class. he makes the subject matter very interesting and is always cracking a joke.

Seriously, this guy's fantastic. He always uses ridiculous examples on-the-fly, but they're hysterical. Laughed out loud in class daily AND still learned a ton. Information is easy to understand and very interesting. Wish he taught more than 3 weeks of the class. Looked forward to his lectures and would often be upset when the 50 minutes were up.

Orrock is a pretty good instructor. His lectures were interesting, but required very active note taking. He answers student questions very well and makes the concepts more easy to relate to. His exam was a fair assessment as well.

He's a cute nerd. Makes nerdy jokes and teaches Ecology and Evolution, pretty boring stuff but he makes in interesting.

He is a nice person. You can tell he's into what he does. His lectures can be really boring though as well as his slides that are most of the time blank, which he then writes the answers on the board which is time consuming and annoying if you want to look at slides online later. Pretty easy, just be sure to take good notes & stay awake.

Generally, lectures were boring outside of a few hilarious jokes he made. He's a great guy and nerdy in the best way. I didn't really take the final seriously because i thought evolution/ecology was so obvious but it was harder than I thought it would be. Least favorite of the three who taught bio.

Great sense of humor and understands that students are as excited as he is. Must say study his examples, those will come up on his exams! By far my favorite of the three lecturers.

Orrock is one of the best professors I've had at Madison. He is very charismatic and passionate about what he teaches and connects well to the class. I was in a power lecture and they didn't seem bad. His exams are not bad and homework is easy. Definitely would recommend his class to someone mildly interested in this field!

Dr. O was great, especially for those trying to get their feet wet in an introductory class. Very charismatic and funny and he clearly loves what he does (which is more than can be said for many). He communicated the information in a clear creative way so that you could remember it. By far the best lecturer in this class.

He had a great sense of humor and seems really passionate about what he teaches. He is clear about what he teaches and is interesting to listen to. His information for the exam can come from the lecture slides or the powerpoint, so you have to read the textbook.

We had three professors for this class and he was easily my favorite. He had great humor and he was confident in what he taught.

He was the best professor I've had so far. He always tried to make his lectures interesting and used great examples to clarify. Very entertaining and very helpful, learned a lot- made lecture worth waking up for.

I really enjoyed his lectures and did the best on his exam out of the 3 lecturers.

An absolute gem of a class required to fulfill the C/D requirement of the biology major. 3 midterms, 1 drops; 1 final. Have to read on1 3 page paper/week. Thats it! Easy class, phenomenal professor!

An absolute gem of a class required to fulfill the C/D requirement of the biology major. Easy class, phenomenal professor!

He actually does his notes by hand! Very clear in explaining the material and let's you know what's important. His lectures are engaging and makes you want to learn the material. Isn't big on detail, but wants you learn the main concept.

Dr. Orrock was my favorite professor of the three. He always had great examples and made sure that people understood the material he was getting across. I would take the class again just for him.

Dr. Orrock is easily one of the best lecturers I've had at UW. He makes ridiculous 90s nostalgia jokes and really lets his personality show through. He also does notes by hand which I respected. This also meant that you need to take notes as his PP contains little info. You also need to scour the text as he pulls the most particular bits for exams.

Orrock is a great professor and a funny guy. It is incredibly important to show up and take good notes, because he takes notes on the board and the powerpoints he posts online are mainly just pictures. There is no textbook and the only homework is to read a short article every week and post a response. Pay attention and you will do well.

Orrock is one of the best lecturers. He's abolutely hilarious and I often found myself laughing out loud in class at his jokes. Content isn't all that interesting, but his lectures are entertaining and the class is easy. No text book, maybe 5-10 minutes of hw a week. Go to lecturer though because he takes notes on the board. Easy class, easy A.

Professor Orrock is very enthusiastic and gives great lectures. He writes all of his notes out on the board so there aren't any online notes, so obviously you can't miss lectures. He was able to break down hard subject with funnyuseful anecdotes. The passion he had for what he was teaching made me enjoy the class more.

Dr. Orrock does his best to make his lectures engaging. He knows his material well and throws in a lot of humorous examples to keep you interested and to help you remember what's going on. He writes his notes on the board, which is really helpful, but that means you also need to show up. Overall, he's a great guy and I look forward to his lectures!

He's probably one of my favorite professors. Ecology really isn't my thing, but the lectures were very entertaining and he makes a lot of examples on the fly, which is great. He also writes a lot of notes on the board, so attendance is necessary if you want to pass. He's a great guy and he knows his stuff.

John Orrock is great! He has the most bubbly personality and his excitement for biology shines through with every lecture! He tends to zoom in on more important concepts rather than go through all the topics from the book so make sure to read, but overall I learned a lot from him and he really wants his students to succeed. Would recommend.

He strikes a good balance between knowledgeable and funny. His lectures tend to contain a lot of material, but he's good at providing examples. He writes definitions on the blackboard so you'll have to attend if you want notes.

Dr Orrock is hilarious, enthusiastic, and knows his stuff. He gives great explanations, and made what I thought was going to be a boring section of zoology very interesting. He writes class notes on the chalk board, which was awesome. His test was not terrible. If you study and know the material, you'll do great.

Dr. Orrok tried very hard to be a clear and relatable lecturer for BIO101. I found him really funny (in a dorky way), and really enjoyed his lecture style. It was never boring. Additionally, he wrote his test in a very fair way, and provided a lot of extra credit on it. Would definitely take again.

His section of this course was by far the most engaging. He gave real life examples and made hilarious references to Snoop Dogg to get his point across. He is a great professor.

Prof. Orrock is one of the best lecturers on campus. He is super relatable and takes the time to make sure he's giving good examples in class. The tests are more than fair, but it is nearly entirely taken from lecture. As long as you take decent notes, this is an easy pass with a good teacher.

Really engaging even in talking about a subject that was pretty boring to me and that I was only taking for a requirement. Helped me understand the material far better than other lecturers I had for the same class over the course of the semester.

I took this course with John Orrock specifically because I had him for Zoo101 last semester & he was amazing, and this semester he did not dissapoint! He is so funny & makes the lectures entertaining. He is great at converying the main points he wants you to know & tries to make things relatable by using fun, "hip" examples. My favorite professor!!

He is incredibly passionate about ecology and does a great job at making his lectures clear. He gives great real-life examples that help you remember the information. My favorite out of the three lecturers.

super nice guy and good teacher. really wants people to do well and to understand his lectures. also very funny

Prof. Orrock is very passionate about evolution and ecology. He tells a lot of jokes and tries to make the information engaging and relatable. His exam was harder than I expected it to be, but I still did well. His lectures are on level with Thoma's, and he is very approachable!

Orrock is definitely one of the best professors I've had at UW-Madison. He's hilarious. His enthusiasm and jokes help to make learning the material a lot easier. He makes the tests pretty tricky, but if you come to lecture every day and study the material for a decent amount of time you'll be fine. Overall, he's a great guy.

Professor Orrock cared very much about the material he was teaching the class which was encouraging. He did speed through lectures and gave A LOT of material. But he is a great professor nonetheless.

He is good based on the lectures, very clear and funny. The exam looks a little unfamiliar is maybe due to the contents.

Professor Orrock is a solid lecturer. Sometimes it felt like things moved a bit too slowly (especially when it was simple material) and other times it felt like we moved surprisingly fast. Overall though he is a good and clear lecturer. His test felt pretty standard compared to those of the other 2 professors for this course (Bement and Thoma).

Orrock was the best lecturer out of the 3. He was funny which kept our huge class engaged and explained concepts really well

He was very funny and lectures were always interesting but he tends to go off topic and then run out of time for the important stuff. I liked him a lot but his exam was the hardest one of the three Bio101 professors for Fall 2018. Make sure you understand his lecture material and maybe try to use the textbook for more information, I didn't.

The middle of the three lecturers we had. Test was trickier than I was expecting although not too bad. Study a good amount and you should not have any issues with this class despite what MadGrades tells you

he keeps the class engaged during class. You can tell he likes teaching.

Prof. Orrock is such a nice human. He is clearly very passionate about what he teaches. This isnt an easy class, but his lectures are really interesting and easy to follow.

He seems very excited about teaching the material and does a great job of explaining the topics. The tests were manageable, but there were some things on the exams that were not talked about in lecture. So, for his section I would recommend reading the textbook in depth. Overall, very laid back professor and fair exams.

Amazing professor. He Is enthusiastic and shares material in an understandable way for ALL students. Overall he was the best bio 101 professor out of the three and his unit was the only unit that I enjoyed.

He was the sweetest out of all professors and his lectures were best! He does mention multiple times that you need to read the textbook and that exam questions from reading are fair game. I did enjoy his content but if I had no prior class about ecology it would have been tough! He is also the last professor in class but gave it a refreshing feel.

Dr. Orrock is the definition of corny but in a good way (in my opinion). His lectures do go off topic a lot but usually it's relevant examples outside of the slides. Writing down just what is on the slides is probably fine.

Definitely a great professor even if the other BIO101 ones might be most people's favorites. He is very clear about what he expects, and mentions multiple times you have to read the textbook (which you do). Lectures are clear and easy to understand, and while he does go on tangents they are relevant and sometimes funny. Overall no complaints

Hands down the best BIO 101 Professor. He was so engaging and taught the subjects so well.

By far my favorite lecturer for the course. He brought incredible enthusiasm to his lectures and the material also wasn't very difficult.

Really nice and funny professor who goes on lots of tangents. At times, his tangents take up the time for actual lecturing and he runs out of time. The topics are interesting and you can tell he is passionate. Make sure to study closely because exam questions are quite specific. Overall, a great class and professor!

Definitely overhated. The test is somewhat difficult, but if you pay attention in lecture and study the concepts, you'll probably be fine. He's definitely a cornball but he's super passionate and he always tries to liven things up with his sense of humor. It made class more fun, and I appreciated that he really cared.

His slides are very word heavy, but pay the most attention to the notes written in blue when studying.
