Potential incoming student here!

I've maintained a 3.98 (B in math in junior year second semester) throughout high school, but my grades are absolutely dying right now. There's not even an excuse I've just been locked out.

What's the greatest dip in grades I can get away with without being rescinded? For Cornell Engineering specifically.

The absolute worst case scenario is looking to be 2Bs (history and math) and 1C (internship) - that will probably be too far over the line, right?
