As it was explained to us; the IFS is intended to be part of the Moody type syllabus where students have that prior flight time plus a solo before going to the new Primary (IE: no API academics first). They're putting people through IFS now but due to the budget it's only a few people at a time and any flight time is a disqualifier. An IFS student I talked to said they're basically using a lottery system now to determine the lucky few, but if your going to OCS in Mar and starting API in the summer, then there may be more people getting it by then. That's a roll of the dice, but I've heard it from the horses mouth that you do qualify for Moody if you get IFS.
(FLASH IFS REPORT: I spoke with that same person in IFS a while back and she said it was hard! The instructor is really piling it on her because he knows she's off to Navy flight school, unlike someone taking lessons on the weekend.)
...but for right now worry about PT and the big 3!
