Hello,
I took the course last year. The test is basically regurgitation of the lecture notes. For example, one question last year was which has the shortest wavelength? (UV, X-ray microwave etc..) or How many light years is the closest star from us. What's the most abundant atom in the universe :Hydrogen. If you review your notes and understand everything, this could possibly be one of the least challenging tests you will write, however the material is arguably the most interesting.
Goodluck.
