Here is the thing about testing be it written or practical. by now you should have gone through enough scenario's and skill stations to pass the test if you don't know a skill or subject well enough by now .. you wont learn it in a few days. My advice would be to study how to take the test, not so much the info contained in it. meaning you should know how why and when to intubate some one after completing the class.. male sure you have the steps in proper order, anything, you would want to verbalize, say them out loud several times a day leading up to your test, you can scan over your class or practical notes but as i've said you should know the material well enough by now, if you feel weak in a particular area then a review may help, if you have the time and money and I don't pretend to know what is involved this 3 day review, but they shouldn't be covering anything you don't already know. Relax and study the skill sheets.
