Hey! I hope I'm doing this right (after 2 months of following this thread, I've just joined this website so yay), but I had a very recent webinar with a few representatives from SMDEP and I have just 2 notes on this^
1. Juniors and seniors definitely may NOT apply. There was a Q&A session for the webinar I participated in and there was a very large emphasis on this. Please, apply as a freshman or sophomore.
2. While there is no bias for "early cycles", the program is first come, first served. Everyone has a fair chance at being evaluated for admission, but only until the sites are filled up. With respect to that, it pays to apply early.
On that note, good luck to everyone who applied!!!!!
