As a person he is great and very knowledgeable about his topic and is passionate about teaching it. On the other hand he likes to play trick questions on exams and quizzes and will keep the entire question the same as previous questions but will only change half the word to mean something else which will completely change the answer.

His lectures are FULL of information and hard to follow or to find information when looking for answers. He puts multiple paragraphs of information on each slide. He will put a diagram or photo on each slide and this is where he will get most of his exam questions. Exams are difficult and he words his questions to trick you. No extra credit offered

He's a great professor. The lectures are full of material, and for me, it was hard to follow, so I would end up going over them again. He tends to just read from the slide anyway. Your grade is composed of 5 quizzes out of the 6, 3 exams of the 4, the final, and then lecture questions. It's a very difficult class, but I learned a lot.

I used to love physiology before taking this class. I started struggling right from the start. He puts WAY too much information on his slides, and it's extremely overwhelming. He also tricks you on exams and doesn't give you help when you ask for it. He told me "well if you attend class and go over past lectures, that's all you can do to prepare"

The lecture slides for this class contain way too much information and are not easy to pick out the important information. If you email him a question, he will simply tell you to refer to the slides instead of answering the question. Additionally, his exams are tricky due to the wording and similarity in the answer options to choose from.

Warning: if you can avoid taking this class I would. His slides are not helpful in learning the material or studying for the exams. He does not give clear instructions and frankly is not helpful when you ask questions since he just says to look at the notes. He's annoyed that only 1/4 of the class shows up, but he's the reason why.

Dr Riddell took a potentially fun and interesting topic and bombarded you with way too much material and confusing slides with little correlation to test material. His ego is wildly inflated for wanting to teach students and is completely unapproachable. I seriously dislike this dude. It's not surprising that nobody shows up to his class.

I have yet to meet a professor that I disliked more. He has a giant ego and isn't afraid to show it. He is not approachable and frankly prevented me from asking any questions due to his rude demeanor. Most times he simply just refers you to lecture slides to "find the answer" instead of simply answering it and clearing up any confusion students had

Loved professor Riddell. He is very personal and easy to work with. Make sure to pay attention in class as he gives lecture questions that could show up on the tests.

Professor Riddell, I thought, was a really good professor. He always seemed into the material he was talking about. I would recommend attending the lectures because he talks about information to know for the exams.

I felt that this class is a good one to take if you are pre-med. The book isn't required, but I would recommend either finding a free version or buying the one he recommends because if there is something you don't understand in lecture slides, he puts the chapter and section where you can find it and you can read more into it to better understand.

Professor Riddell is extremely knowledgeable, professional & passionate. He goes well into detail and then some to keep you interested in the topic discussed. He loves to answer questions & his explanations are on point. He could do a whole lecture on lizards if you let him. This class goes into physiology of humans and animals. 10/10 recommend.

I enjoyed this professor.He makes the lectures interesting.Even though it is not required,go to lectures because they are really helpful for understanding the information.A book was required.However,I didn't really use mine as much. I got all of the information I needed from the lectures.I liked that we had three days to take the exams and quizzes.

The class can be really tough if you don't show up to lectures. Unless you are one of those people who can absorb information from a textbook like a sponge; show up to lecture. He is funny, he's young so he isn't out of touch with his students. You get three days to take the exam, which is really helpful for people like me with a full schedule.

There is participation questions on canvas after each lecture that you get full credit for even if you get them wrong, those questions often show up on the quizzes and exams. It is always very clear what will be on the exam and if you follow his guidance exams are very approachable. The content can be tricky, but I recommend Dr. Riddell.

Very clear grading. Good professor. Do the readings and study the participation questions/questions asked in-class and you will do fine on the exam. Worst exam score dropped!

The exams are tough if you don't go to lecture. The exams have a good amount of questions you've already seen in lecture and on quizzes. There are extra credit opportunities which is really nice.

I appreciated a professor who truly wants the best for his students - and takes time to make sure they understand the material. However, the material covered on exams are heavily based on lecture and the post lecture questions. Overall, the class was interesting and I was pleasantly surprised by the effort put into each lecture.

Excellent professor. Always engaging with students, accepting of questions, energetic, and encouraging of small-group discussion in lecture. My favorite professor at ISU thus far as a junior. I would suggest him to anyone looking for a biology course!

He is a very good professor and makes it into terms that are easy to understand. His tone of voice used makes for a fun lecture, not boring. I enjoyed listening to lectures, even for topics I did not care much about. The tests were pretty hard, so going to lectures and paying attention is how you do well in this course.

Dr. Riddell was a great professor and made this class very enjoyable. Participation questions discussed in class are used on quizzes and exams, so if you attend lectures and pay attention you should do well. The textbook is optional, but I found it very useful to reinforce concepts.

Overall, Riddell was very enthusiastic in class, which made going to a morning class more enjoyable. Riddell generally always made it very clear about what information was critical to the exams, gave great feedback when it was asked of him, provided extra-credit opportunities, and was fair about grading exams when some questions were not "fair".

I believe everyone has the ability to pass this class. Take note of questions asked during lectures, participation questions, and quiz questions, as they will most likely be on the exam. GO TO the LECTURE, I cannot stress that enough. A lot of the content touched on in class will be on the exam.

While attendance was not mandatory as there was no role call, I would highly suggest attending lectures. Lecture skipped are hard to understand as he goes through concepts and questions in class. I would also suggest reading the text as it felt like half of what was on the tests were not directly on lectures.

Attendance isn't required but lecture powerpoints are hard to understand if you don't go to class because they are just figures from the textbook and no text of the major points he wants you to take away.

The homework is a lifesaver. A lot of the material on the exam is very similar, almost word for word, to the homework/quizzes.
