Hey Artshep,
I'm sort of in the same boat. I just took the test last month and did pretty well in the quant (48) but absolutely bombed the verbal (28).
Based on my GMAT prep test, I believe SC was the biggest pain point. Of course, on the actual test, I had to guess on the last 7 or so problems b/c of timing and I missed one of the RC passages completely.
Regardless, I am somewhat familiar with SC structure (passive, idioms, etc.) but still seem to struggle.
Can you offer any pointers that really helped you with SC?
