The service academies are constantly trying their best to improve the cadet averages each year, whether those averages are subscores on the CFA or standardized testing scores. They almost always succeed in doing this, raising 3 or more averages if 1 drops down, so it's unlikely that this year will be any exception. The service academies always find the best of the bunch.
Now, with that being said, it is still possible. On occasion, scores drop from one class to the next, and it's just the best of what was offered to the academies. That doesn't mean to lower your standards, though, and you should never prepare less because you expect the challenge to be less difficult. Act like the scores have gone even higher than than they normally would be at, and strive to land fitness and academic scores above that bar.
Worst case scenario? You receive a good CFA or SAT/ACT score that remains competitive.
Best case scenario? You receive an excellent CFA or SAT/ACT score that is highly competitive and may be the extra mile needed to make it in.
Best of luck on your journey!
