Though I haven't taken the GMAT, I feel like this strategy has more chances of going wrong than helping you, but I might be wrong.
IMHO, like someone mentioned above, missing questions in a row would result in more penalty than missing questions spaced out. I think you should work on pacing yourself better than try what you mentioned. And if you feel like you're not ready to take the test in a week, there's no harm in postponing it a bit so you can be more comfortable with the Verbal. As it was mentioned in one of the debriefs, you should take the GMAT when you're ready - not a moment too soon or too late.
And I actually think that the RC is one of the places where you can get your answers right even if it looks long and boring at first. The questions are almost always direct or inferring to the passage. As many have suggested before, just skim through the passage, and try to identify the one main thing they're saying in each paragraph.
For instance, the first paragraph might introduce an opinion, the second provide counter examples and the third might conclude by saying that though there are other evidences, the opinion from the first paragraph is still mostly valid. Doing a cursory overview in about a minute or two will help you narrow down the answers a lot. I wouldn't advice on completely taking the RC for granted by selecting A for everything.
Also, there are some questions on the RC which refer directly to certain lines in the passage. These questions should be easy to follow. I would suggest working with the
OG or maybe even the
MGMAT RC Guide for a bit to see where that takes you.
I might be wrong, but I feel like this might help you! Hope it did!
