I'm taking the lsat in-person next week and was wondering if anyone has any advice on what I should take aside from an ID?

Do i need to bring my own scrap paper and pencils or do they provide it?

I've been working on my RC, and it's gotten better but I keep getting inference questions wrong. I get around a -8 on RC and 3 of those are usually inference questions. So far, I just keep practice drilling, but does anyone have any tips on how they handle inference questions? Or any advice on how to improve?
