They were mostly in a range from really easy (identifying the lewis base/lewis acid in a reaction, calculating pH, some stoichiometry) to medium level (basic questions on calculating Ka or using Ka to find concentrations of different ions). The most difficult question was really only difficult due to the amount of information and constants given and the number of steps (like 10) taken to solve it. I'd say it was at a first year college chemistry level. And I didn't need to know anything that wasn't in my Chemistry book. It was much easier than the acid/base test for my AP Chem class though. Of course all tests are different, so you can't really expect other tests to be similar.
