Pre-College Programs at Brown

So I was recently sent a post card from Brown University advertising their Pre-College Programs and I was wondering 1: If I was sent it, does that mean I have a good chance at getting in? 2:Do colleges look upon it favorably when looking at possible student’s applications?
I really would like to do it because they have some really cool programs on their website but I don’t know if I would be accepted as I am not that good in freshmen grades(3.3) but I did step it up this year with some IB and honors classes to get a 4.1 for this semester. This is along side working on my eagle project, looking for internships, volunteering, and being in clubs. Any help would be appreciated :smiley:
