Nathan is not understanding of online environment, cares too much about "in person" conditions . Even with webcams turned on, not enough time to complete tests and quizzes and one question is displayed at a time. this class is definitely made harder online

One of the worst professors at UFV. He is very knowledgably in the material but is possible one of the hardest markers ever. His lectures are long and dry and he expects you to know things he doesn't talk about. The textbook questions are extremely hard and don't relate to the tests. DO NOT TAKE BIO220 WITH HIM!!!

I was confident that I understood the 220 concept until I took this profs midterm. His grading is tough, expects you to answer questions in a specific way. Multiple choice questions are twisted sometimes. The assigned textbook questions aren't helpful at all, they aren't similar to exam format/concept

No curve, not caring, bad at teaching- lectures are too vague, does not prepare for exams. Extra questions from book not useful. Labs are boring. Grades way too hard/unfair, will get my grade appealed after this. Save your gpa, do this class at some other uni. not worth the headache

I don't think Nathan is a 1 star prof as seen by some of these reviews, I think he'd be better irl. I agree about the MC sections on his tests, they can feel like an english exam sometimes. For his online class he doesn't do a live session so if you want to pass go to his office hours at least once a week even if you don't have questions.

Nathan was not accommodating to the online classes at all. He made this class a lot more harder online and his assessments were very unfair and hard. Different students would get different questions since they were randomized due to being online. Some students get easier questions than others. Very hard marker. His lecture notes are not detailed.

The best prof at UFV. Taken 220, 401, and 409 with him. DO NOT take his classes if you're lazy and looking for an easy A. Definitely take him if you're actually looking to learn something. Incredibly smart and well respected, he wants you to succeed (if you're willing to work). I spent time in his office going through questions before every exam.

Is so knowledgeable but he is a hard marker. Does not give part marks even if you got part of a question correct or if it isn't worded the way he wants. His quizzes are easy but you need to go to his office hrs if you want to do good on the midterm/final. Study everything in the PowerPoint & write down everything he says and study that too!

I really enjoyed this class, it was a lot of work and you need to put in a lot of time to do well. Nathan made himself available for extra office hours when needed and went out of his way to made sure you understand all the concepts. He is a tough marker and wants a lot of detail. I found the final MUCH harder than the midterms

Go to his office hours, it'll be the difference of a grade letter if you do. Very tough marker with high high expectations for his content. Don't just KNOW it, have it be a part of you because the test/final questions will take you out. Final exam had a question worth 9% of the overall test and it was a deviation of a formula we used once.

Nathan was just alright. Genetics can be a challenging subject - Nathan definitely made it palatable and interesting. Final was much much more difficult than the quizzes and midterms. He has a tendency to have trick questions in exams, rather than just testing you on knowledge.

Excellent lecture and lab prof. He was one of the most caring and down to earth profs I have had at UFV. I really regret not taking him earlier in my degree! Super welcoming and open for questions and office hours, and very dedicated to his students. Not an unreasonable marker at all, highly recommend.

He is a very stellar lecturer and does whatever he can to set students up for success. But his midterms feel too short on time and are arguably a little too difficult or vague. I wouldn't take him again due to the difficulty he gives and the little practice or study material he provides for midterms in addition to the practice textbook problems.

Despite genuinely doing my best in studying; memorization of the lecture notes is often not enough to succeed in exams. As frequently questions require extensive thinking that is otherwise not really too easily touched upon unless you had hard practice problems outside of the textbook he recommends to do questions off of. I would pick someone else

Lab only, Out of 20% total lab mark - 15% quiz, 5% assignments. Quizzes are modelled after assignments and the lab reports, but make sure to pay attention when he goes over the lab procedures as he hints towards what is on the quizzes. Didn't find him to be a strict marker for the lab, though labs were very long. Nice guy otherwise, fun to talk to
