I just passed my RPAL and PAL. I aced both. They are ridiculously easy!
Written - very easy - 25 true/false and 25 multiple choice. T/F - all safety and common sense. Multies - I do not know who can get those wrong because three other options is a joke.
Practical however could make you or break you. We had two guys failed because one had finger on the trigger and one pointed muzzle to the instructor (duh!)
Very important to keep your trigger finger off the trigger and point muzzle in the safe direction when manipulating with firearms. If you did not get where the safe direction - ask again! Before practical test they give you practice as much time as you need and if you do not feel comfortable about particular firearm action or how to prove safe/load - ask again and again until you can do it yourself. Safety is what they are after!
If you want to see what kind of questions they ask, go to gunexams.com and take written test for free. It will give you an idea. For trial written you do not need to pay. If, however, you are completely paranoid

, you can buy 1000PAL and 1000RPAL - 25$ each package and practice your a$$ off till tuesday.
Relax, breath, everything will be just fine! good luck
