Rosner is kind of chill. He doesn't curve the test which is kinda booty but he does lower the grade range. I got a 82 and that was a B+. He has one midterm, one final, and homework. Homework is kind of chill until you miss one thing and lose half your grade all of a sudden :(. He does this thing where you do the homework and if you make it look like you tried, you will receive full credit. But you have to submit it again with the correct answer the following week (he gives you answer key). His lectures are straightforward. I liked how he made steps to solve the problems he gives, but the lectures were quite boring I would find myself playing clash royale to pass the time. He doesn't record, but posts notes, however his handwriting is also kinda booty. He writes in cursive which is odd for an engineer. Go to discussion people. The TA's were so clutch this quarter. The professor lets you take 3 cheat sheets for both exams and the TA's give so much helpful information. Overall though I think it's fine to take this class with him. I honestly liked doing statics and strength so take that into account when reading this review.
