hi...i am preparing for step 2 ck but struggling to find a good source for epidemiology and biostat prep. i am using mtb2 and 3 and they have not included these topics. what should i refer to??
can anybody plz guide me.
all i have is kaplan notes as the only option and i dont wanna get into extensive studying for these topics. i want sth precise that i can memorize and recall too.

First Aid for the USMLE , student to student guide, is the solution complementary...
