Concerned about being rescinded from Carnegie Mellon [4.0 -> 3.71 (12th fall) -> 2.86 (12th spring)]

2 As (in easy classes), 2 Bs and 3 Cs. I can probably get one of the Bs (in Spanish) to an A as it’s very high and I have a lot of late work in that class. FWIW my counselor said I wouldn’t get rescinded but I wanted to send an email just in case + people here seemed to think it was necessary.
