I am not very sure what the 93QT score means, the results sheet you get should explain what the letters stand for. I do know that the practice test doesn't really count for anything, it is more of a prediction of how you will score on the real ASVAB. The MAGE is the four categories you are scored on. Mechanical, Administrative, General, and Electronics. Medical AFSC's should mostly be based on your General (G) score, with minimum for some of them being in the 45-55 range. However, the job slots are handed out based on your ASVAB scores, and the needs of the Air Force will come first. If they only have 10 spots, and you are number 11 on the list based on your scores, you will most likely not get that job spot. The ASVAB score doesn't really have an average, because the number score you get is based on how well you did compared to other people who take the ASVAB. The number is what percentile your score falls into. The best advice I can give you at this time is to talk to a recruiter, because they will have answers for all of your questions, and it is their job to keep up to date on things like this.
