Since our class trend followed with past years so far, I would say that meeting the 3.6 in the Fall will probably be the same for the upcoming class. About 50% of the current class met the Fall benchmarks. That being said, I feel the schedule for the fall semester was far more rigorous than the spring semester schedule which contributes to some people not meeting benchmarks. There are tons of students who were super close to meeting benchmarks in fall but were just a few points off, say had a 3.58 but needed the 3.6.
As for maintaining the 3.6 in the spring semester for next years class, I do think it is still doable because the spring semester (at least for us) looks much more reasonable regarding exam scheduling and pacing, so I don't think it would be too difficult to maintain a 3.6 or higher in the spring semester. The benefit is that the overall by the end of the year needs to be a 3.6, so if you demolish fall and get higher than a 3.6, you can afford to get a tad lower than a 3.6 in the spring, as long as your overall still remains 3.6. (I'm making this assumption based on what is currently in place for us since I am assuming they only changed the actually stats needed.)
