Worth Retake for Integrated Reasoning? I finished my first attempt today, I ended up with a 730 48Q,42V but 4 IR. Overall score is better than expected, but my Quant was a little lower than I hoped and the IR went really poorly. 

I messed up my time management on IR and had to randomly guess on 3 of the 12. I think with some more practice (I really didn't' put the time in I should've across the board), I could get the IR score up and do better on Quant, but I am also not sure I'd do as well on the Verbal again, so I don't really expect to get too much more than 10 or 20 more points on the total score if I'm lucky. 

Is the IR bad enough that it is worth a retake?
