I just got my writing approved today and my score immediately afterward. I honestly recommend just keep calling LSAC until they relent. Not fun but that's what worked for me. Good luck and sorry about the wait, I know it's frustrating!

Hang in there friend! The road has twists and turns and you should certainly be proud of how far you have come. Some time off to clear your head definitely sounds like a good idea. Best of luck with the journey!

I believe they are one of the most common question types on the actual test.

I really appreciate this advice! It's important to be skeptical about blindly trusting everything we come across (even if it tends to sound like it is "correct"---such as the wording on the LSAT----due to its complexity.
