Do You Have to Do the Top Levels in One Day?

I like the idea that the different teams had different levels in all of them, minimum, a medium and ceiling could be used to check where you are fitness wise. But what i couldn't find anywhere is, how did the lasierra students trained to achieve the different stages? And did they have to do the test in one go? I know that you did not have to do their top level in one day. We did this in my school, southward junior high, which i thought this programme was fantastic. we did the testing, and i can't remember if we had ten or 12 things, but we did them in a three day period. Now, it doesn't sound like much
