howdy. i'm in a somewhat similar situation. i've got 4 years of college under my belt, but only 1 math class taken within those 4 years (only 1 math class was required for my degree). 5+ years ago in high school, i received all A's in my algebra and calc classes, but I need a waiver because I dropped out of Algebra 2 Honors, and took just plain ol' Algebra 2 instead (got an A in that). Alg. 2H appeared on my transcript, but with no final grade. my recruiter assured me that i need to get a grade waiver for that, and he has never seen a grade waiver rejected. he also said that when considering passing or rejecting waivers, they may or may not take your asvab scores into account. i may have to take the NAPT despite my score of 99 on the ASVAB, because i've only taken 1 math class in the past like, 6 years.
in addition, he also informed me (although he was not entirely sure) that there is a point system that the navy uses in order to determine your eligibility for the nuke program based on the math classes you've taken within the past couple years. for example: a grade of "A" in an algebra or higher level math class is worth 20 points, "B" is 15 points, etc. he also said that how long ago you took the math classes affected how many points they were worth. AND he also said that if he was indeed correct when he heard about this, then the requirement is at least 50 points. but he could be wrong. god only knows. i await my phone call today which will tell me whether or not i made it in.
he also told me that the nuke program is currently locked out for females. you're in a better off situation than i am at the moment. best of luck to you.
