Studying

Having some doubts about me passing a test, which I have to pass in order to keep my job! I guess this test is really difficult. It is 5 1/2 hours long and almost no one passes the first time it is taken. My biggest problem is sitting down and studying. I have never been one to study and have always "passed"....but never really did anything more than to just pass. The studying bores me and I end up falling asleep on my books. I don't know what to do. I am going to set up a plan for myself in the next day or so and have to work on breaking down the parts I need to learn and hope that is enough. I don't have much time to learn everything. Hopefully I can get a 70% or better and just "pass".
