Toughest class I've ever taken. So happy I'm not medical major. Anyways, I've got to salute Doc Quack for teaching me more than I wanted to know. There were a lot of people who had trouble, but hang in there, study the in-class assignments and lecture questions and you'll do fine. I hardly find any of his jokes funny, but at least he tries. He taught me how to pay attention to the small stuff, which is important. The only problem for me was that he couldn't memorize my first name.

I was under the impression that he was a tough but good professor while reading his reviews from other students. He's really condescending and hates if you ask too many questions. He does not like repeating answers, and if you didn't hear him the first time, tough luck cause he sure as hell ain't repeating it the second time.

Don't take this professor unless you have no option. Even then put it off till next semester. His grading style's unclear, he will not answer additional questions and displays favoritism towards the students he prefers. Most of the time it's ladies he's showing favoritism towards. He does not like interacting or teaching, and yet he is a professor.

I knew he would be tough but this was the hardest class I had ever taken. He is unreasonable, unapproachable, and not understanding. He will put you down, make you feel dumb if you ask too many question, and actually call you out in front of the whole class. If you need to take this class I would suggest you do it somewhere or with someone else.

I regret taking this professor. I love biology, but he makes it such a chore and stressful subject than it should be. Biology's a difficult course because of how much you need to memorize, but he makes this class so difficult that only the students he wants to succeed will succeed, and if you're not on his good side, he will put you down.

Very interesting & funny teacher made bio enjoyable, but his unstructured style is only suited for intro classes. Hard to learn because his lectures are all over the place. Although I got an A I am not sure this class has set me up for success in future biology classes. Grading seems random. Test questions could be better instead of "who said this"

He obviously has a lot of enthusiasm when teaching, but this class single handedly made me despise biology. He goes against his own syllabus at times sometimes even answer the question asked. He wont let you ask questions before or after lecture and sometimes doesnt even show up in his office hours. Dont take this class if you want to have fun.

He is a very straight forward teacher, he gave out "golden rods" which are essentially study guides for his tests. What I found out at at the very end of class is that the tests are nearly identical to the golden rods. If you're able to memorieze the golden rods you will get at least a 90% on the tests, remember the animals he mentions they show up

Inspired me to like biology. You have to work hard to earn your "A" grade. He has an awesome personality, at first he has his guard up, eventually if you make conversation with him you see he's a great person. He cares for his students. Gives opportunities for extra credit. The Golden Rods best invention!!! Always has an answer for a question.

Looking for an easy "A" move along, but if you enjoy learning and putting in the effort to earn your grade take this class! He is FUNNY, charismatic and full of knowledge on the subject. He offers support when needed and always available during office hours. The Golden Rods are amazing. Don't be late, stay engaged and have a blast learning Biology!

Great Professor, very fair, straight forward. Golden rods are KEY. He is a life experienced person, and does not live in an academic bubble. Gives very fair opportunities for extra credit. Being an older person I found this very refreshing. DO NOT judge him prematurely , or get butthurt, he can be a little guarded at first . Gifted professor.

He made us use "golden rods" that are supposed to be study guides for the exams but hardly anything was the same. He made rude comments towards students in the class sometimes. Saw him at office hours a few times and he helped there but still didn't help much. Took the class with someone else and I passed with an A! Do not recommend.

This Professor is AMAZING! He is the best Professor I've ever had, lectures are so fun and was never bored. He gives weekly GoldenRods (not required to be filled out) that are exact questions as exams (same format + short videos he shows halfway through lectures) Took him in the summer and he still gave us an extra credit opportunity worth 20 pts.

This teacher is good but he is very tough. Classes are heavy lecture and if you ask a question he makes a face before he answers it. He scared one of my other friends who also took his class. DO NOT TAKE HIM IF YOU WON'T PUT IN THE WORK!!!! I cannot stress that enough... grade is heavily based on quizzes, and tests. Make sure you study A LOT!!!

This class is definitely way more difficult than it seems at first. Tests are graded on an all or nothing for questions worth up to 10 points (out of 50). With how few things are graded, tiny mistakes can really cost you your grade, as can missing any time in class. If you miss a test even for medical reasons you get a 0 with no chance for makeups.

his class would be ok if he gave partial credit, but if it's not exactly how he wants you don't get any credit. he's a tough grader and his grading system is by points so tests and quizzes aren't worth more. DON'T TAKE THIS CLASS IF YOU'RE NOT READY TO WORK!!

Don't be fooled by the "for liberal arts" attached to this course. It is complex, and note/lecture-heavy. I highly suggest using a laptop to type out the lecture notes because he goes through topics SO QUICKLY if you can fulfill your lab credits another way I would!

Doc Quack's class is very straightforward. He gives weekly golden rods which are basically the exact same as the tests. If you memorize the Golden Rods and the short videos he shows in class you are almost guaranteed an A on all tests. He is quite funny and interesting and offers a ton of extra credit.

This guy is awesome! You can definitely spend a lot less time studying for tests than you would be doing homework, which he didn't give. Expand on the Golden Rods a little bit but don't work yourself up over the amount of information he shares. He really cares about the subject and made class a good time.I always looked forward to going.

I genuinely cannot begin to describe my hate for this professor. The amount of information he introduces in every lecture is astronomical considering it is a 1 hour lecture. And he doesn't spend enough time explaining his subject considering the amount of new terms and concepts we have to know by heart. DO NOT take this class.

Very lecture heavy, doesn't expand on new concepts so you have to research them yourself out of class to understand. However, he is very passionate about his subject and makes it easy to not fall asleep during lecture. Lab is almost completely independent but don't feel afraid to ask questions or for help. Golden rods are essential to succeeding.

His classes are very lecture heavy, however the content is not very complicated as long as you spend a bit of time outside solidifying your knowledge on the topics through videos. Quack's lectures are genuinely hilarious and keep you awake, and labs are almost completely independent, but don't be afraid to ask! Golden rods are key to tests!

Whenever I would come to school I wished I got ran over. He grades so HARSHLY, hes so lecture heavy and he doesnt even explsin the material + grades by a couple things so if you dont do good on tests youre screwed. Hes also not understanding and rude. I hated this class so much. His golden rods dont even help at all on the tests. Do NOT take him
