Just received my USMLE CK score today morning. Thought I'd share it with everyone.

Study time: April 2015 - August 2015
Materials used: USMLEworld + DIT videos.

NBME 7: 210 (before I began studying)
UWSA: 237 (3 weeks prior)

Real deal: 227

Most important study tip: Less is more. It is better to read one book 10 times than reading 10 books once. Stick to one reliable source and break it down. Know it inside out!
