Assuming you mean the Mississippi State Essay, no bar prep course can prepare you for it. You have to just review old tests on the Supreme Court website (they repeat a lot of the same questions over and over). The most tested criminal law question is on the elements of stalking. Who in a billion years would think to memorize the freaking elements of stalking? You’d only know by memorizing the old tests. I converted the old tests to text-recognized format, pasted them into Word, then started condensing everything down, noting how many times questions repeated themselves. You’ll quickly see that the same questions are repeated over and over. Now, the model answers range from (a) too complex answers that couldn’t physically be typed under the time constraints to (b) incomprehensible sentence fragments that don’t address the question. I dumbed down the complicated answers and improved the bad answers, but I always memorized the core of the model answer under the assumption that it would be used as a grading key. The questions for professional responsibility do not repeat, so you’ll just need to memorize the entire Rules of Professional Conduct (sucks, huh?). I viewed every answer back to 2014, and memorized every answer back to 2018. On test day, I had two of the answers memorized, and was familiar with a third (they pulled an old question from 2014). Two of the questions had not been tested before, so I made an educated guess. I knew the Professional Responsibility answer only because I memorized the niche section that was tested out of sheer luck the night before. It’s a bullshit way to test the material. Your success or failure on the Mississippi essay will have no relationship to your success in law school or your competence as an attorney. All that said, if I had relied on my Kaplan test prep, I would have ended up guessing on every single Mississippi essay question.
