U simply can not practice, except to brush up on your speed distance time maths! (first test of the day, along with the Interrupt test)
You have applied for Air Traffic Control... wouldn't you be a little angry if the testing were so easy & so many unsuitable people got through & your life were in their hands???
I didn't look at it this way until I said to a friend, "The interview was hard..."! He said, `Well thankgod for that, I fly alot & would hope only the best make it through'...
You can either do it, or you can't. Best you find out at the testing days as opposed to during the college training!!
Read the forum again.. all the advice is in it.. rest well, don't stress, forget about one test as you move onto the next & have confidence in yourself that you have the aptitude to do the job!!! :-)
Goodluck!
