This course is difficult to begin with but Rafter helps a lot in clarifying any questions or concerns. There is a quiz everyday so do the hw and you'll do fine.

This man is a legend and for a reason. He can and will answer any question you throw at him in a clear way without ever being negative. This is likely his one of his fav sub to teach, and it shows. The exams were the hardest I've ever taken, but he gives so much partial credit. Great guy, difficult class, super cool material. Take if you love math.

I'm gonna go against the grain here, even though I know this won't affect his rating. I wouldn't take this class again. Rafter is a good prof, and a talented lecturer, but his grading just feels very punitive. You'll probably learn a lot, but don't take him if your GPA matters. I promise I wasn't expecting an easy A, so ignore at your peril.

John Rafter is very clearly passionate about two things: math and teaching. He is very fair, however he does expect an incredible amount from his students. I'm not sure I've ever learned more from a class, but that means there was a lot of work. Frequently worked 8+ hours on the weekly problem sets. DO NOT TAKE JOHN UNLESS YOU LIKE MATH!

Math 1300 is a hard class to begin with but Professor Rafter is a hard grader. His tests are extremely challenging and the most important thing is to practice the challenge problems because those will be among the easier questions on the tests.

Professor Rafter is very knowledgeable about math but is not a good choice for math 1300. His lectures are often proof based despite not needing to know proofs for the exams. His tests are the toughest out of the math 1300 professors. The questions are not problems seen before in the homework. He does curve exams and the final grade at the end.

If you have to take MATH 1300, choose John Rafter. He's by far the most generous math teacher that I've ever had (not to say that you can slack off). He proves things in class, so that you can use whatever equation or theorem for homeworks.
