The material isn't all that interesting but I definitely recommend this professor for 120A! This class was co-taught by Prof Liu (first half) and Prof Holyoak (second half). Prof Liu did his best to explain the complicated information but his accent was terrible so it was hard to follow. I preferred the second half with Prof Holyoak. Unlike many psych tests, Prof Holyoak's were straightforward. Do the reading and study his lecture notes. He explains the material very well so attend lecture.
