Today we had a review period for the exam. There is a review for students to study but you should make sure to look over all previous assignments, homework and labs for this unit.
The exam outline is as follows: True and false section, multiple choice section, diagrams!!! (angle of deviation, lateral displacement, refraction, lens), problem solving. If you want to have a look at the formula sheet for the exam, it is linked in the blog post from last Friday.
