Get enough time to complete your solo before you come down to IFS if you have a little time and money to burn. IFS is another easy way for the navy to cut people right now on top of all the other rising bars, so having the pressure to do well in IFS reduced would be well worth the money at this point. I see plenty of people down here sweating the pressure wishing they had spent a little cash to get some prior flight time. You probably already spent a small fortune to get a degree that is supposed to help you out, why not spend a little more to help get some confidence in the air while you have the means?
