Just take your time, rule out one that you know is wrong right of the bat, do not read more into the question then it is asking you, Make sure you know OB/GYN, Medical emergency's, and ventilation rates, And you should be fine. I took mine on 7-29 and it was not nearly as bad as i thought it was going to be.
How do you like the emt-national site ? That is what i used and the questions on there are twice as hard as the exam so if you are doing well on that, example on emt-national I was scoring in the 80's and 90's on all sets of questions and reading the rational on all the ones I got wrong and that helped me a ton, I was doing around 200-300 questions a day.. Good luck and let me know what happens I am sure you will do great..
