I studied for 4 weeks. I read the Secrets in order, then read B&W, then re-read Secrets in order. All the while doing around 6 blocks a day in tutor mode @ UW. I'd finished Secrets about 4 days before the exam. Then just did UW over and over (about 8-10 blocks a day) while reviewing my notes from tutor mode. I'll know if it worked in 3-4 weeks.
Some of my friends were using Crush, others the Kaplan books. I felt pretty comfortable with the tutor mode on UW plus Secrets and B&W, so I stuck with that. I may have answered the same question on UW wrong 4 times, but I reviewed it 4 times when I read over my notes.
