I have gone through CK before step 1. Now I regret it so much. I spent 7 months studying and I had 92 (222).
A lot of the questions depend on you having even the slightest idea about step 1 material. Also studying in this order is much easier. I think even if somebody had the highest score in CK before he studied step 1, he could have done better if he did in the right order, especially for IMGs as we are not familiar with American basic science teaching.
