I was today years old (2 years of studying LSAT) when I realized "the only" was group 1....

A LOT of questions. Any tips on figuring out the best ones to use? Should we just go by gut reaction/what speaks to us?

How up to date is everything? For example, I believe the UNC LSAT median is 168 now, not 167. Is this just splitting hairs?

I don't think you'll find an answer to either of your questions. You can even look at Reddit for past official test dates like June and usually there are instances of both 3 LR, 1 RC and 2 LR, 2 RC discussed and the order can be pretty much random too. I know I got 3 LR then 1 RC last time I took it in June

So I would say just be ready for anything. One thing you can do to address your concern is doing endurance drills like a 30-question LR section (adjust time accordingly) or a 5-passage RC section. This way, just 1 section or two back-to-back sections of the same type shouldn't bother you too much.

I think you could do 2 things: 1) depending on where you're at with your studying, you could always go review those parts in the core curriculum, 2) probably more immediate, drill these areas. Make a custom drill with conditional reasoning questions only, maybe set to 3,4,5-star questions or just 4&5. You can start with untimed work then progress to timed. Aim for 100% on those drills before moving on. Repeat with causal reasoning.
