Step2CK and CS.

Here is how I did it in Step2CK.

Books. All kaplan. In step2, books won't help that much. The Mcqs will.

Give two reads to all kaplan books except psychiatry, for that step1 BS is more then enough. Next buy the online Kaplan Qbank, do it mixed timed, in 15 days, with noting the explanations down on a separate register. Then, buy Usmleworld Qbank, again online and mixed and timed, do it in 15 days. In between these two Qbanks, one should do an NBME Form 2. After doing all this one is adequately prepared, and this is the max prep anyone can do for Step2ck. Ideally this should enevr take more then two months, but I had issues at home, so the timing of my Step2 weren't as ideal as those of step1.

For Step2CS, usmleworld and firstAid books. Prep4usmle.com forum, neeraj CS notes, arletes CS thread, both on the forum, and a lot of practice with a live partner or with someone who is also preparing for this exam on skype.

Let me know if any further info is required
