I did not attend SLE but as far as the CFA goes, I found that you don't need too much time to prepare. For my CFA, I was pretty good for the running and pull ups because I had been practicing regularly. However, my push ups and sit-ups were terrible (I didn't have good endurance) and my Bball throw was weak and awkward. I spent two weeks doing 200 sit-ups and push-ups a day (not all at once, I used a variety of sets throughout the day) in order to get my max up. Then I spent a few more weeks just maintaining and adding a variety of exercises to help. I also spent two weeks practicing the Bball throw for about 45min everyday. On my actual test, I ended up maxing out in push-ups and sit-ups with time to spare and my Bball throw was 79ft.
If you need a workout plan Stew Smith has some great, free, online workouts for passing PT tests of all kinds. I encourage you to try them out. Anyways, the point is don't be scared about not having enough to time to prepare, just get a solid workout plan and stick to it. Remember, with all of the events, PRACTICE is everything.
