Just took my TPR diagnostic exam. Scored a 489. Is this pretty average for a diagnostic with no review? I've been out of college for about 4 months now just working and haven't taken anything related to the sciences on the MCAT since last fall. My toughest section was biological sciences and I think it was mainly because I felt like I hit a brick wall about 1/3 of the way into that section and just could not focus to save my life. Rest of the sections were about what I expected.
