While summed up well above, the million dollar question is how many applicants are there currently in college - not naps, foundation,etc - just in college on their own reapplying - that's the missing puzzle piece. If one looks at past years, historically there are some (38-80) admitted that would seem to fit this catagory - not counted within naps, foundation, or fleet numbers.
