We have 3 unit exams each 33% and 1 final which is 50%. My first exam in med-surg was 52 on MS. Everyone says the second exam is harder since it deals with Neuro. I'm very nervous. Is it possible to recover from a 52% in Med-Surg on your first exam? We need a 75 to pass the course. Our instructor makes her own exams by the way and she does not use any test banks. What you think is important was not on the exam.. Is there any hope for me? I studied my butt off.
