"i was pretty skeptical of exam prep sites in general, had a bad experience with one before. but cocexamprep.com was different in that the case-based questions actually felt like what showed up on the real thing. not identical obviously, just the same logic."

"failed my first attempt, came back and used it to drill ICD-10-CM alot more systematicaly. second time felt alot calmer. open book doesnt mean easy, you still have to know where to look fast."
