I learnt every law in the book and could cite them parrot fashion up to the exam day. My advice would be to use the card system. For example, write "state rule 29" on the front of the card, then write the rule on the other side. Do this for every rule you need to learn then go out for a long walk (better than sitting in your room) and learn them keep reading and reciting them until it is second nature. Ther was only one thing I did not know for the exam which was one definition which I could not fit in to my head and I was too knackered to learn. It came up in the exam and I got 98%.
