Believe it or not . . . I have used the same AIM YOUR BRAIN Study System to help my students prepare for their Step 2 CK exams.  We are planning to write the combined STEP 1 and 2 book in the future after the exam is changed.  But for now, use our Step 1 book. It works.  If you have additional questions, email us at info@ideas2pen.com.
