I think the hardest part of the LSAT is learning to spot the logic behind an argument under time pressure. I find that even when I understand a question, two answer choices can look almost equally convincing, and the small differences matter a lot. One thing worth updating here is that Logic Games were removed in August 2024, so the current test focuses on Logical Reasoning and Reading Comprehension. Personally, I think consistent practice and understanding why wrong answers are wrong matter much more than simply doing hundreds of questions.

I'd find a module like this pretty useful, especially if it focused on the basic math concepts that people tend to forget rather than trying to teach an entire math course. Things like percentages, ratios, averages, basic algebra, and translating word problems into equations would be a good starting point.

Personally, I learn better when I can see a concept explained through an actual example and then try a few questions myself. Short lessons followed by practice problems would probably work better than just a list of formulas. It would also be helpful to have a quick diagnostic at the beginning so people can identify which concepts they actually need to review instead of going through everything from scratch.
