With three weeks to go, you may feel like you need to already have everything memorized. You don’t. That would be impossible. You have plenty of time between now and the exam to get the law to stick.
Remember to stay in learning mode. Right now your days and nights are filled with memorization and practice. While you should be moving into doing practice closed book, that doesn’t mean you are expected to have everything memorized perfectly. It’s important to practice writing down what you know, and reasoning through the rest.
Every time you do an essay, MPT, or set of MBEs, think about 2-3 lessons that you can take away from that experience and carry with you to a similar fact pattern in the future. Write these lessons down. If they are rules, put them in your outline. If they are test-taking tips, keep them in a separate journal or on a separate list.
Everything you do is in service of internalizing and memorizing the rules. True memorization takes time and repetition. It won’t happen overnight. Fortunately, you have just enough nights left to make it work.
