You certainly have a chance but it’s an extremely hard school to get into. I wouldn’t worry at all about your first semester freshman grades. If you’ve had a 4.0 since then they aren’t going to care about that first semester and if you don’t get in it won’t be because of that. Just as an FYI, I was valedictorian, had a 4.0 unweighted with all the hardest classes, high SAT, outstanding EC’s etc and applied REA and didn’t get in. My high school sends 1-2 students to Stanford each year and my friend who got in this year actually had 2 B’s on her transcript Fall Semester Senior Year plus a boy got in for sports. What I’m saying is that it’s hard, but also I don’t think you’re freshman grades will be the deciding factor. Good luck to you!
