You may be able to get away with those higher average times IF you pick a certain number of questions to just let go. You can still get a decent score this way, though you likely won't be able to score 80th+ percentile on verbal.
Is that acceptable to you? If so, you'll need to random-guess quickly on about 7-8 questions in the section (more if they're all SC; fewer if they're all CR - but I wouldn't make them all one question type).
That'll save you about 10.5 to 12 minutes across the section.
But I'm going to suggest a few other things to try first.
When you spend 2.5m on CR, where is that time going? How much time do you spend reading? How much time do you spend on the answers? If your reading speed is slow and it takes you extra time to understand the argument, then you may be stuck with that.
A lot of people, though, waste time on the answers. Here's the answer elimination process:
- 1st pass through answers: place answers into 1 of 2 categories, definitely wrong or maybe. DO NOT decide whether something is right at this stage.
- 2nd pass through: look only at the "maybe" answers, compare, choose one
- When you are down to two answers on verbal, look at each answer ONCE more, then pick one and move on.
Are you doing that? People often lose time trying to decide at stage 1, when you can't know yet because you haven't looked at all of the answers, or stage 3, when people agonize back and forth multiple times over the same two answers.
On RC, you say that you often take 5 minutes to read. You are almost certainly reading too carefully / too deeply. Pretend you're about to go into a meeting with the CEO of a potential new client. Your boss asks you to review the summary of the company's most recent annual report. The summary is 6 pages long.
The meeting starts in 5 minutes.
What are you going to do? :)
You're going to read, yes, but you're also going to prioritize. You're going to pay attention to the "big picture" information and leave the details for later. You get to keep the summary with you, so you can always glance down to reference a specific detail if needed.
That's what you're doing on this test too. You're not actually trying to read everything carefully and thoroughly understand it. You're just trying to get the main ideas, the big picture - and you'll go back into the passage later for any necessary details. (Which you're already doing anyway, because you can't really remember all of those details after the first read-through, right? So skip trying to learn them all on that first read-through.)
But, if you're already doing all of those things, then you may need to do what I referenced at the beginning: accept that you're not going to be going for an 80+ score on verbal, plan to skip a certain number of questions spread throughout the section so that you can maintain a steady performance to the end.
Also, in terms of keeping track of time, what I do for verbal is Method Two in Section 5 of this article:
http://www.manhattangmat.com/blog/index ... nt-part-2/You group the questions into four "chunks" with the expectation that you'll get one new RC passage in each chunk. As long as that's true, the time works. BUT you keep track (I make a dot on my left hand with my pen every time a new passage pops up). So if I've already had 2 passages by Q10, then I know I should be a bit more behind on time. If I haven't yet gotten a passage, I know I should be a bit ahead of time.
