My real test time was at 1pm, so that is when I took each practice test. I would review content in the morning, typically looking at outlines that I'd made for each Kaplan chapter and doing some of Kaplan's subject tests to reinforce content, but nothing passage based that required extensive reasoning. Then I would review the test the next afternoon at 1pm, again doing content in the morning.
I studied pretty intensively like this my last 3 weeks before taking the test, and did 6 practice tests in the 13 days before my test - one every other day, and nothing but relaxing and some easy content review the day before my test.
Then again, I just took my test Thursday so I can't vouch for your success, haha. But I felt pretty good about my methodology and preparedness. Just hoping it translates on the real deal.
Good luck...
