External monitors are not allowed, per my understanding. https://www.lsac.org/about/lsac-policies/lsac-candidate-agreement

"Please be aware that your Test proctor will not allow you to take the Test if any prohibited electronic devices are observed during the room scan portion of the check-in for your Test. This includes, but is not limited to, any separate monitors or desktop computers that are nearby during the Test."

Nope! Probably in the next couple days they will.

Yes, scores are definitely higher because of the Flex (and other factors like more apps + more time for folks to study) -- and seeing medians up across the board.

I mean regardless you should aim for the highest score possible! If you're applying next cycle, I would assume that the median for a particular school will be 1 point higher.

Interesting. It's the opposite for me. I really struggled on the paper test, but have seen my score go up +8 on the Flex. Totally just depends on the person I think.
