I kind of felt bad for Mills, he is a science guy teaching a prerequisite class to non-science majors who didn't care at all. His lectures are pretty good, he loves "Simpsons" references. There are 4 exams, study and you should pass. The labs are a bit dull but he puts everything on Moodle. And he's a cute silver fox.

Prof. Mills was an amazing prof. Yes his class at times may seem dull but it is obvious that he has a passion for his field. I'm not much of a science fan and needed a good NATS course for G.Ed. Exams are all multiple choice and there are 4 and short! Anyone need a easy A (providing you attend all labs and go to lectures) This is def a bird course!

Mills is a fantastic professor. I've taken three classes with him so far, one of them a field course, and he's been great in all of them. I can't speak for 1001, but can note that in upper year classes, he places special emphasis on the scientific articles he references. Study those just as much as the lecture material, and you'll be fine.

He's kind, understanding and explains concepts well. If you took grade 11 and 12 bio, you can get an easy A in NATS1660.

Dr. Mills is by far the best prof. He's so nice, I don't think I've ever seen him be rude or get mad, he takes the time to answer people's questions and if he doesn't have time during class, he copies the chatbox on zoom to respond later. Super friendly & explains the material really well and you can tell he likes what he teaches.

Professor Mills by far the best biology professor I have ever had, he teaches enthusiastically and always answers your questions. He wants his students to understand the material and does not want to give a lot of homework and activities at the same time. Definitely would like to take another class with him.

He's absolutely amazing. SO respectful, kind and caring and I would love the opportunity to take the course with him again. And while all sections tried to make this course easier for students, Dr. Mills by far made it even easier! Seriously is an amazing professor.

Best professor in the past 3 years in York! He cares about students, gives feedbacks and very fast responds all the time, and even offers extended deadlines over the weekends. Class materials are not really hard as long as you listen to the lectures and have gone over the provided powerpoints. You will not regret attending his class!

An extremely patient and genuine guy. He does his best to make the class enjoyable and will stay after class to make sure everyone understands the material. Assessments were fair and reasonable, and grading was especially fair during the pandemic.

From the very beginning Prof Mills tried to make this course easy and fair for students. Even though I had his class at 8:30am, I did not find myself falling asleep to him, as he had a good pace & kept things interesting. He was very knowledgable and cared about his students. I don't think I will have a class with him again and it makes me so sad!!

one of the easiest A's i've ever gotten. since the course was online he made the tests open book and the labs are easy as long as you pay attention to the lectures. overall he's a great guy and genuinely cares about his students. his lectures are also based off the textbook so you don't even have to buy it. I would definitely take him again

Had for a Field Bio Course in the summer, was one of the best profs I've ever had! Very engaging with our little class and was very knowledgeable :) Wish I could take more classes with him, definitely was a very considerate marker and his quizzes and assignments were very fair. I expect his non-field courses to be equally interesting and engaging.

He was the best prof I have ever had at York and in my life. He made me want to switch majors to biology. He is passionate about what he teaches and so resourceful and highly educated. For the first time in my life I'm sad that a course has ended. Def recommend.

Prof. Mills is probably my favourite prof at York. His tests are extremely straightforward, and all the material you're tested on can be found in the textbook or taught in lecture. 10/10

I took BIOL 4520 without a very limited knowledge of birds and I left with a lot of knowledge and a new interest! Prof Alex is really passionate and knowledgeable about birds and you can learn a lot from him. He's very caring towards his students and is always willing to help out. His tests are application based which may be difficult for some.

Professor Mills is a fantastic instructor who really cares about student success. The course material is manageable if you stay engaged, attend lectures, and utilize resources like the provided textbook and Unstuckstudy for study prep. Overall, a great class that I'd happily take again.

I took BIOL 4245 & 4070 with Professor Mills this term. These courses are by far the best courses I have ever taken. His teaching style allows for learning from mistakes and constant improvement through the advice he gives on tests and assignments. His use of examples that are applied to every concept taught has expanded my knowledge of nature.

I took a field course with Alex in the summer of 2023 & it was a wonderful experience. I learned a lot from the hands-on experience and there was a very supportive learning environment from both Alex & my other classmates. He had great lectures & great feedback. He got to know you on a personal level & always wanted to see you succeed in his class.

Birds with Professor Mills is very straightforward. He is great with questions both during/after lectures and points out important details you should focus on. The lab portion is very fair as well. Midterm and the final were both extremely well-written and rewarding for anyone who attends lectures regularly.
