It might help you in deciding which electives are for you. The pre-req is LS2 and Physics 6 or 1A. PS107 is only offered Fall Quarter. If you have taken LS2 and either Physics 6A or 1A you can take PS107 as early as your sophmore year. However, the majority of students are juniors.
Labs meet the first week of class and some labs meet before the first lecture.
It is really important to keep up with your assignments in this course. Lab and lecture are coordinated. PS107 is not graded on a curve so you are only competing with yourself. The pre-reqs are LS1, LS2, LS3, LS4, Physics 6C, PS107 and one organic chemistry course. PS111A is only offered Winter Quarter.
