@moonyoung_8 we can't compare this year's timeline much to last year, although I also go look at last year's threads to see trends.
This year TMDSAS Match Day March 5 was so close to Resident Match Day March 15 that schools are busy with this overlap.
Usually the TMDSAS WL activity begins a week or two after Baylor releases another round of acceptance offers, and Baylor hasn't made that announcement yet this cycle. This happens when some people who hold a TMDSAS school after Match day might relinquish it when they get a Baylor offer.
