at api.. for the first four weeks your mornings are full of swim. you shower, change clothes and go to class. get lunch and have more class. sometimes your days end around 2, some days around 5. overall the academics seem a little overwhelming at first. some people obviously will have to study a little more than others.. but once you get your mind wrapped around the material, it's not too bad at all.. last two weeks, mornings are later and days end earlier with the survival classes, dunkers (which are easy even for nonswimmers), and parachute training..
in primary, i spend about four to maybe five total hours at the squadron on a fly day.. some days you'll be scheduled on standby hanging out in the ready room in case someone else cancels. other days you'll be waiting around on the weather. typically spend an hour or two before each flight studying procedures and discussion items at home. sims take about two hours out of your day.. the rest of your time yours.. duty is different for every squadron, but it's no big deal.
overall, you should enjoy flight school much more than tbs...
