Hi DesertEagle. Here are my general GMAT verbal pacing tips:
SC:
1:20 average, never exceed 2 minutes
CR:
2 minute average, never exceed 3:15
RC passage + 3 questions
6:30-7:30 (depending on passage length), never exceed 8 minutes.
I suspect if you're falling that behind, some of it is 'answer dancing.' You're dancing back and forth between possible answers, trying to get every question right, when you should be making a good guess and moving on.
There are also general ways to increase speed. SC, for example, is often about finding the most important words for that question, and not about reading every word of every answer choice. But I suspect step 1 is adapting to the mindset needed for the GMAT's scoring algorithm, which requires a comfort with guessing and moving on, and understanding that you will ALWAYS miss a bunch of questions on this test, no matter how good you get. Have you done some research on the GMAT algorithm?
