AMAZING. Ratner is very passionate and caring professor. The grade breakdown of this class was very intimidating because it was heavy on one midterm and the final. If you go to lectures, read the readings, and study a fair amount you should do great in this class.

Ratner is an amazing professor and genuinely cares about his students. He is so amazing, I had to come on here and write a positive review for him! His class was interesting and clear. For tests, he doesn't try to trick you. Class is graded only by a few things. He is a really awesome professor and teaches really well. Super caring & wants to help

Really interesting lectures and content that was organized pretty well. Make sure to understand the experiments covered in lecture in addition to the other material. Exams were straightforward.

Love this professor and this class. Lectures, quizzes, and exams were very well structured. As long as you understand the experiments and what they mean, you will do fine on the exams. The only complaint I have is that the article summary was graded super hard, but other than that I loved PSY 105 with Liberman.
