My association uses a combination of the rules test and floor evaluations in their ratings. For us the rules test is taken closed book.

The best advice I have for you is READ THE CASE BOOK. Especially the cases applying to the new rules. Typically in the test (in case you haven't noticed in the past) there will be a question word-for-word out of the case book.

Look at it this way... If you don't know the rule inside and out, how can you make a correct interpretation on the floor.
