Could I get a waiver for a technical point on the ASVAB?

You need to look in the mirror and ask yourself this question with all the honesty and character you posses: Do I have the requisite level of education and general knowledge to create a base to build upon and am I really smart enough to fully understand and absorb the training to become a medic? All of us, if we are men or woman of character, can answer that question to ourselves. If you cannot say unequivocally yes, than serve your nation in some different MOS

Maybe, but wait- you want to be a medic, using all kind of upcoming tech changes in the medical field, and you couldn't pass the general tech test? Why should anyone want to trust their life to you? Think maybe your dreams/wants are unsustainable?

Study some more then retake the test. When I do Recruiter's Assistance with the Air Force yhats what I tell applicants. You have to work to get what you want. Plus that shows us that you are motivated and that builds a case to helping you out. Also start taking a few general course college classes. That has an impact to.
