Yeah, practice the 5 miles bro... ours was a timed 3 miles run (can't remember what the time limit was, but faster = better score). Always a good thing to practice more than needed.

The real killer for me was the shuttle run... god to this day I HATE shuttle runs!

beep! run, stop, beep! beep! run back, stop, beep! over and over and over, faster and faster... ugh.

I found the shuttle run a LOT rougher than the 3 miles run as it is run all out, stop, run all out, stop...

As for stairs, I highly reccomend you practice it on real stairs... stairmaster machine just isn't the same.

Good luck with the exam bro!
