He claimed that he has no curve in this course, but somehow, my friends and I receive a better grade then we expected in the final and also the final letter grade. Midterm is chill, similar to AP STAT if you learned that, Final is heavy, be careful for that.

If you find yourself know nothing and the final is coming soon, don't panic. It's possible to learn all the things with 2 days if you have a basis of things taught before midterm, then, you should put effort in past exam he posted in canvas, work through every questions carefully (you will see similar ones in final), and view the recent HW.

Brian's chill but lectures were kinda a snoozefest ngl and I found it easier to try and learn stuff myself. For the midterm, time is the real challenge. Question's aren't overly hard, but you have to work efficiently. Final is much harder and it took me almost the full 3 hours. Homework is hard but solutions are posted so its pretty much free.

Good lecturer and explains the material pretty well. One midterm, which was very easy, and a final which wasn't too bad. Section attendance is mandatory and you just go over homework problems.

Lectures were fairly engaging, although there's way too much information on the slides and it gets impossible to follow at times. HW is a free 50%. But final was absurdly difficult based on everything else he assigned; it brought my grade down an entire letter. You'll be fine as long as you study MUCH more than you think you have to for the final.
