The official answer will probably vary from unit to unit, but the way we did it was that you'd have a PFA during indoc/orientation week to see where you are. If you pass this one*, you did not have to do remedial PT. If you failed, it was no big deal scholarship wise, it just meant that you were on remedial PT until the real PFA.
*My unit used to consider "excellent" passing. Anything below excellent and you were on remedial. For scholarship purposes you had to actually fail to get in any trouble.
There's no trick to doing pushups (or situps, or any exercise). If you suck at them, do a lot of them until you can do more. Challenge yourself to do a set number every day and then raise that number by 10 or so every week.
