Good luck in your quest to attend the SLE next summer. My son went to SLS last year and enjoyed it a lot.
One thing that surprised him was the CFA. He had worked pretty hard to do well on the CFA. However, after flying to New York on Sunday and then taking the shuttle to West Point, he was pretty tired. The CFA for him was the next morning (Monday). Needless to say, he did not do as well as he thought he would after working on the events for the preceding months.
I might suggest when you begin working on the CFA, at some point begin doing all the events one right after the other. I think you might be surprised how the number of push ups may go down after you have completed the previous events. I think you might be surprised how slower your run might be after you have completed the previous events. I know my son was dumbfounded with how tired he was after the accumulation of events.
He retook the CFA a month later and improved each event considerably. Gratefully, they (and the other Academies) accepted his second CFA. I think I have read somewhere that about 40% of the people fail the CFA at SLE/SLS. While he did not fail his CFA at SLS, it was clearly not what he anticipated.
Again, good luck. If you don't get in to SLE/SLS, don't worry about it. My son did not get into the Navy's NASS and yet received an appointment there (he's in Plebe Summer right now). BTW, he also received an appointment to West Point.
