I scored a 102 in the MM category and I needed to get a 104 for the job 15T. Can my recruiter round my score up?

lol

If that was a thing it would actually round to 100. You can retake the test. Just prep properly and have a good meal and a good nights sleep. You can do it.

Your recruiter doesn't even have access to your score. The MEPS controls your score. You can find some asvab study guides to practice before you retake it
