I am sorry but this is just not true. I was in the previous 1 yr MM class and can tell you that only 18ish people got accepted from both the 2- and 1- year cohort. Last year, they accepted around 29 if I recall correctly. So yes, MM class sizes are going down, but so are the acceptances. It's not like they are accepting a larger percentage of MMs from it.
I also want to note that only 8 out of 30 in-state people got in, and 10 out of 12 OOS people got in. And some of the OOS students had lower GPAs than some in the in-state group that were not accepted. Throughout the year, the MM program director said that she believes 30 MM students will be accepted this year but clearly that was not the case. She also said that they have reserved a few seats for the MMs so that they don't "repeat what happened the year before," which was clearly a lie. Unfortunately it's not her fault as adcoms will not communicate with her properly, which to me sounds like adcoms don't really care about MMs.
This Master's program is dying and I am glad that it is. It's very broken and needs a complete rehaul, like a guaranteed acceptance policy or even a conditional acceptance based on your final grades. But no, if you don't get in during the first wave of acceptances, you just get put in the waitlist with every other non-MM applicant after your final exam. They don't care about you, period.
