2 people from the place I took it had their scores voided. It's a fairly good idea, especially if you know you didn't do well. But, I feel as though I'd like to know my score, especially after paying $180.
Start studying - it'll be nice to have a long, relaxed studying schedule for next April. Good luck to you! I might be taking it again too.
If you want more advice, PM me....I have taken the MCAT a couple of times and I know the feeling you are having. The best advice I have is take time off now, you will be able to do the exam rotten in April if you relax now.
PM me if for specific questions. If you are graduating next spring, let me know.
