Skipping Multi-Source Reasoning?

Hello,

I have run into incredible timing issues on IR and have considerable difficulty with Multi-Source reasoning in particular. For some reason, I just get stuck in 5+ minute holes trying to simply get the gist of the issue, and it kills my timing for the entire section.

In all of the IR sections that I have taken, I have never got more than 6 of 12 correct, and generally have to guess on the last 4-6 questions due to completely running out of time. My accuracy on non MSR questions is extremely high, and I have no timing issues on these whatsoever. Confusing MSR questions are taking me in the realm of 12 or more minutes to complete the 3 question set. I have gone through probably 6 or 7 of these so far and just cannot get in the swing of efficiently answering them.

Given that I am currently getting 6/12 correct anyway, is there any good reason not to skip MSR questions? On the official test, I had a particularly confusing MSR that ate up way way too much of my time and sunk my entire IR section. I do not know the weighting of these questions off-hand, but for me, it seems that an 8/12 or 9/12 with MSR skipped is far better than a 6/12 with some MSR correct.

The only problem that I can see with this approach off-hand is the possibility of getting two 3 part MSRs in a single test, which would absolutely kill me. I suppose that by the second one, I could safely spend the time to understand it, given that I have opted to skip the other.

Any thoughts or comments would be appreciated. My most recent test scores have all been between 720 and 760, but the IR section has been quite vexing to me.
