Used uworld, combank, DIT, secrets (the weekend before my exam) and savaresse and got 686. Step 1 was 604. Here is my breakdown:
Started DIT about 5 weeks prior to my exam. I finished that in 16 days then hit uworld hard. Did 3 blocks of 44qs daily with full review and annotation into step up. About 2.5 weeks before my test date, I started combank. I finished combank in 1.5 weeks. The last week, I combined uworld and savaresse (about 2 hours each night). The weekend before I used secrets. I took a comsae 16 days before and scored just under 500.
I would say take this exam when you have a super easy rotation. My schedule was ~7-10 am for that whole month. If you can't manage that, just take some time off. It's worth it if you're applying DO. Study the **** out of OMM-- I had so many OMM/OPP qs. Use uworld and a comlex qbank. There is no match for uworld! I didn't think combank was bad! Secrets was okay but I don't think it gave me any new info. It was nice to flip through it the weekend before. DIT was nice for the schedule it kept me on!
I had a lot of qs on my exam about ethics/medico legal/Medicare issues. I guess I'm not too sure if I could have better prepared for those...
Overall, I walked out not knowing how I did. So glad it's done!
Sorry forgot this:
Uworld avg: 66%
Combank: 74%
Also, I think 5 weeks was too long... The last week I was so burned out that I felt like I wasn't retaining much.
