Twice I have taken the actual test; I got 2 RCs both times. One time back-to-back RC. Like the person before mentioned, stamina is very important. Practice for it. I think everyone should be prepared for the possibility of 2 RCs. Good luck!
Fatigue may be a factor, as I get pretty drained during the test. I'll start practicing the two back-to-back and consider adding a 5th section of LR to build up stamina. Thanks for the suggestion!
