Miami Dade College partners with Baptist Memorial and Jackson Memorial Hospitals to offer a "scholars program". These programs offer full scholarships
as well as stiffens for books and uniforms. The are highly competitive to get into.
Currently I am a nursing student at Miami Dade College. I started this fall. I got the same letter last June...and had the same questions you have. Since the application time frame for these programs is longer (they look at a lot more than GPA) they need invite the prospective students with information about the programs sooner rather than later.
When I went, they told us that we are not yet accepted into the program.....but.....here is all of the information for applying for a scholars program. The very next thing said was "have all this stuff filled out, all the letters of recommendations, essay..etc..etc....so that when you get your acceptance letter....you can submit it immediately).
So...the long and the short of it is......if you get a letter for a "special mandatory information session" you are pretty much accepted.
Not sure why they do it this way....but that's just they way they are. You should get an acceptance letter in a few weeks. I got mine in mid June for the class that started in August.
Hope to see you on campus.
