How do we prepare for this exam? Do we use resources for Step 2 CS such as First Aid, etc? Any suggestions? Thank's. On a side note, MCCQE Part I is not too hard of an exam to pass. I thought the level of difficulty is similar to Step 2 CK, though more clinical. You should do questions from usmle world for step 2 CK. I took the USMLEs many moons ago (I am a 3rd year medicine resident in the US). I tried to do some questions from usmle world (I only did a couple hundreds questions because I was working in the icu and such) and I did not have toronto notes.
