How many questions on the exam and how much time is allowed to write it? then calculate the amount of time you have for each answer.Be sure your up to speed on looking up code rules and applying them.
Take your reference material and know it by heart.Do one book at a time.The average person will need to read/do it three times within 72hrs for it to be committed to long term memory and then weekly there after
Pre exam courses are great because there will be people there that have failed test and have a better understanding of the exam content than the instructor.Pick their brains
Don't skip questions when you write the exam.
Do your best to answer them then write the question # down so you can go back if there is time.
Try to remember any questions that gave you a hard time and write them down when you get back to your car in case you've failed and have to rewrite.
Go to bed early and have a good breakfast
If its multiple choice pick the best answer.Typically there will be more than one right answer but one will be more correct than the others.Look at wording of the question cafully
Finally these exams are not meant to be passed the first time you write.They are looking for a certain state of mind/way of thinking.
