First of all, many congratulations on passing level I exam!
Maybe what I am going to say is nothing new, but after my experience with level II exam, I have to say this:
KNOW YOUR FORMULAS!!
Level II is “item set”: 20 sets, 6 each; most of them are related to each other.
I forgot ONE formula in one section, got < 50% in it!! However, I managed to pass borderline!
Good luck to all of you
