Also, I've been doing the GMAT Club Math Tests, but I'm doing terrible on most of them. Should I be concerned?
Everybody is - don't be concerned - they are designed to make you sweat.
About the questions, you have obviously done quite a few and practiced for a long time. I will send you a PM. However, my score is not that much higher, so not sure how much value I will add. Perhaps somebody with Q50 can weigh in too.
You have a PM!
