Having 6 RC passages in a single GMAT is certainly outside the expected range, but with the GMAT you need to be prepared to face the unexpected. I can understand how this would be a shocking situation, but there is a solution for this problem. Even though RC passages require some up front reading time, the overall average time per question should still be 2 minutes per question. For example, on a short passage you should spend 2-3 minutes reading the passage and a minute per question to answer. If you maintain a 2 min/question average on RC, you could theoretically get an entire test filled with RC passages and your timing would be just fine (though you would probably be bored stiff by the end!).
To improve your timing on RC, study the passages as par of "timed sets". As you run through the RC passages of the OG, first calculate the amount of time you should take to finish all the questions and stay on the 2 minutes/question average. Use a stopwatch (on a phone works great) to make sure you are staying true to the timing.
