the better you do during your first two years, the more you will remember and the easier it will be to review for the boards at the end of second year....I can only speak for myself here, but I did well during the first two years, especially during second year, and it carried over onto the COMLEX I (680/98%).....the second year has a lot of material that will show up on the boards, especially at NYCOM because the second year has all the clinical classes in it (all the medicine and subspecialty classes) that the COMLEX loves to test.....also, whenever your professors point out something that they say will likely show up on the boards, pay attention to it because it probably WILL show up on the boards or on the shelf exams during your third year
