>...What have I gotten myself into?

Kevin,

For the price of a study book you will now have seen every question which could possibly be on the exam in its final format.

As you go through the test you should have a blank paper provided for you to write notes on. Write down topics that you need to study more of. You can't take this paper out with you but you can "memorize" it and then hurry to your car and write it all down.

You may want to note questions that you should comment on during the comment period.

If you've never taken an exam before, be sure to go through the tutorial. Also, watch the notes that say how many answers to choose since choosing only 2 when you should choose 3 is incorrect.
