We generally recommend to go in order. It's less important to do that in RC than in LG, but we're not too sure there's a lot to be gained from skipping around. If you've read the passage well, you should be ready to answer both general and specific questions. If you were almost out of time and didn't read the passage properly, then you might try to answer a few specific questions and skip the more general ones, but it's best to plan for a less desperate approach. :)
