Hi..I have found your CCS series and this question bank highly useful for my preparation.I have used USMLEworld in the past and have failed the examination.The CCS portion of the exam, I believe was my demise.This question bank is ending soon for me and I would like to know how much a 2 week extension would cost as I am hopeful to take the exam before the year\’s end.I had to interrupt my study due to care for an ill family member. Thank you!
