Carlsson is a good teacher. He's very conceptual, and his tests have true and false questions on it. These hurt students the most. The computations aren't difficult at all. Just know the material and how to apply the material. His lectures are kind of confusing and don't have much to do with the tests. Quizzes can be difficult but help with tests.

His lectures are completely useless since he doesn't mention what reading to do before class and his handwriting is awful. As a result, most of the class can't follow the proofs he regurgitates from the text. He rarely does examples for solving problems. He expects us to understand concepts, yet all he does it rewrite proofs.

Tests WOULD be easy IF there were no true/false concept questions which make up usually a whopping 20 points on the test and cause people to fail. Computation problems are easy enough as quizzes and homework help. Lectures are completely useless and full of useless proofs. He doesn't do example problems nor take the time to explain the concepts.

Extremely concept-heavy professor: as other ratings say, beware of true/false questions that will really challenge you. Very generous curves, though, possibly because of aforementioned T/F questions. The rest of the problems on tests and quizzes are not extremely difficult. If you're not really a math person, see if you can get someone else.

Prof. Carlsson gives theory-based lectures. There is not a lot of application of the math. The first half of the class was the most difficult for me, with a lot of theorems and proofs. The homework is optional but you should do it to better understand the material. There were two midterms and a final, all difficult. There is luckily a big curve.

Okay, Carlsson is very theoretical and I can admit to being lost the first two weeks of class. I would say lecturing is easily his biggest weakness, so if you find lecture useful you might want to take Moore. However, everything else is very laid back. HW was useful and interesting, office hours were great, and tests are representative of material.

(Spring 2022) Honestly the main barrier in the class are the lectures. He's not great at teaching or conveying information to the point where it kind of leaves you to self-teach for the exams. Make sure to go to every single review session, some hints are included regarding the MTs and final. Otherwise, good luck...

I don't understand why this professor recommends another textbook. (not Gilbert) He doesn't use this book actually, and this book is really terrible. He doesn't have notes on Canvas. The classroom is embarrassing, it's hard to concentrate.

It's safe to say I didn't learn much from his lectures. He's not very helpful in office hours either and doesn't provide many resources for students. However, his grading is very lenient, so would recommend if you're good at self-studying. Read the textbook and watch the MIT professor on YT. Otherwise, it will be a huge struggle.

Dr. Carlsson is one of the worst professors I've had at this university. His lectures are terrible. He is a sloppy writer and speaks in only abstract math terms. He could at least come up with analogies, but no. He also doesn't even post grades on canvas. Emailing him won't do anything. He doesn't respond.

Everything's bad except excellent curve. You need to go to lectures because he has no recording, no lectures notes for canvas, and bad handwriting. Homework is quite easy to complete. His tests may be very difficult but trust his curve and that other classmates will be worse than you. (For example I got 70% for final but the average is around 40%)

Professor Carlsson was not a great lecturer, as he mostly talked about the concepts of linear algebra in abstract terms and he would use the blackboard (which was so hard to read!). The HWs were pretty confusing and the tests were another level of difficult. But, the curve is amazing and even if you do badly on the midterms/final, you'll be fine!

Very conceptual, difficult class that is exam heavy. He is not a great lecturer, as he just writes down formulas and derives them without explaining their significance. It was hard to read his writing as he used the chalkboard. The curve is good, and through review sessions and Youtube, you can do well, but do not recommend taking MAT 22A with him.

Genuinely just awful lecturer. Speaks in abstract math terms first day and self studied ever since coming ahead of the curve.

If you can self study well use this curve to your advantage, otherwise steer clear.

I tried my best to understand Carlsson's lectures, but no matter what, I honestly left more confused than I started. 22A material itself wasn't too hard and thus was not the worst to self study, but that is what it came down to. On the bright side, he is caring and brings great energy to the room, and he curves really well, curving 70's to A's.

If you have an option, do not take him. If you don't have an option, still don't take him. Lectures are progressively impossible to understand, exams have low averages because your knowledge is tested on your self studying skills as lectures are more of a pass time than a learning opportunity. A pile of stress of a 3 unit class for no reason.

Very bad. Incoherent lectures and homework is loosely based on his lectures. Abuses math logic notation. Lectures scratch the surface of the course content so the best bet for this class is to just self teach from his weird provided textbook. Exams aren't too bad if you can self teach the content. Tremendous curve though so that's a plus.

Prof Carlsson teaches as if you are already well versed with the content, lectures are theory heavy, it doesn't even make sense to attend lectures.

His lectures are a lot like 3blue1brown videos, where they're really hard to understand but elegantly made. But if you do understand them, you'll be fine. He also has insane curves on his tests, the first midterm an A was a 56 percent and the second midterm an A was a 70 percent. I'd say not to take him unless you enjoy math because he is hard.
