Has anyone tried these? I've done a few and I find them to be difficult, especially the physics ones. I was wondering if anyone benefited from these. I realize they're not mcat-type questions, so I don't want to waste time if it's not going to help.
I thought that they were quite useful when i was initially reviewing stuff. If i was you, i would be focusing on the passage based questions at this point in time.
I also found the subject tests useful for testing how well I understood the physics material. But they are actually DAT practice tests, not MCAT, so I agree with the previous poster that you would be better off doing MCAT style passages rather than the subject tests, unless you are extremely weak in your physics knowledge. If you want to do some extra optional problems, do the AAMC practice items instead of the subject tests; your Kaplan center will have them.
