Hopefully this helps...when you're in API you will take the official Navy PFA/PRT at least once and you will be subjected to the regular standards. However, you could be asking about the PRT we take for the physical and the random ones they throw at you. For these PRTs...they only require that you do 50 push ups, 60 sit ups, and run 1.5 miles in under 12:00 (for a wood chip trail). Keep in mind this has been my API experience so far (A-pool) and it could be different for you. I don't know if you can opt to swim or not.
