My input on rule statement on the MBE vs. essay. I am of the opinion that a rule statement is NOT an exact template that you must regurgitate for full points on the essays. There is no one right way to say it.
Understanding the concepts is one effective way I found for "memorization" of the law.
As long as you convey the right
concept—which often includes the right elements of a rule but not necessarily numbered lists like formulaic black-letter law—it should not affect the application of the rule statement embodying the concept.
That is one reason why I advocate for understanding the rules rather than solely rote memorizing them. Just because you know a physics formula does not mean you can apply it!!! You're not a bio or psych sorority girl who merely needs to memorize and know in theory to regurgitate back at the grader.
1. Know and understand the issues
2. Know and understand how to raise the issues (you don't just throw in a bunch of issues in nonsensical order)
3. Know and understand the rules (which often involves a lot of memorizing but NOT the other way around)
You can probably get by knowing like 80% of the issues and rules and still wing it and hope for some ancient piece of memory to unconsciously carry you through.
However, you can become enlightened through practice. Practice will help you achieve all three of the above. (Use model answers or sample answers or a BarEssays subscription to compare to real answers that are below and above (and if possible, at) a score of 65 (PM me for $20 off).) Even if you don't know the law yet. You probably won't know all the law anyway. You'll forget or panic or have never seen it in your life (like the one paragraph in the CMB about variance that was a significant issue in 2014...wtf?).
On actual bar day, you may be able to recite the rule perfectly. You might have to modify it a bit depending on what the facts focus on. You might have to make it up. Most likely it won't be exactly the way you've read it in your outline.
So should you study the MBE law or the sample essay? Neither and both: There's no need to worry about which "version" of the law is right, as long as it's in the same jurisdiction (general MBE law may differ from CA-oriented law).
Learn and read outlines if you want. Just don't stop practicing. Creep on that shit like a poorly raised man trying to escalate kino and never stop ogling and fiddling with essays.
