You seem strong with what you are stating. I can't recall if the AFOQT is 15 or 20%, but as a STEM major with a cgpa of 3.32 and at least a 98, you should be sitting pretty.
~ If I recall correctly, AFOQT, PFT and CGPA are at least 50% of the score. The remainder is the CoC and that also has a very unique formula too.
~~~ Somewhere in the bowles here is the exact formula. Look through the threads for last year SFT.
