I had like 1.9 GPA in college with tons of failed and dropped courses and still got into the Nuke program. This is what you have to do:
Pass the NFQT (which you said you already passed I think)
Get your recruiter to put in waivers for every grade below a C (or C- maybe) that was in a math or science course.
IF you didn't fail anything in high school just don't turn your college transcripts into the recruiter (my advice)
Once the waivers are in, you MIGHT have to interview with whatever nuke is in charge or your area, mine was over the phone and he asked me if i wanted to succeed and would work hard, i said yes, he said ok, then I went to MEPS and was in.
hope this helps
