Hi LiquidFireAK,
One of the variables in pacing your way through the 4 RC passages and accompanying questions is the length of the prompt. Longer passages, by definition, take longer to read. When you factor in the difficulty level of the language, the amount of time that you spend reading can also be affected.
Advice will vary on this subject, so here's what we teach: You're not just reading through the prompt, you're reading AND taking notes. You DON'T need to understand every word and you DON'T need to take notes on every little detail. For this phase on the process, you should expect to spend 4-5 minutes ON AVERAGE. Shorter passages take less time, longer passages take more.
This will give you about 1 to 1.5 minutes for each of the questions. With the notes that you've taken, and the ability to refer back to the passage as needed, you'll be able to find the correct answer faster than if you just went straight to the questions and tried to "backtrack" your way through the prompt.
