Whats the bar for getting rescinded from top schools?

from schools such as WashU, GT, Vanderbilt, what is the bar for getting rescinded? My high school career I’ve had 20 A’s and 3 B’s. Is it ok if I finish senior year with 6 B’s and 1 A? (This is what I’m predicting will happen). Keep in mind my B’s will be a range of B-, B, and B+.

If it matters, I’m applying for STEM majors and my STEM grades will remain above a B.

anyone?

If your admission offer lists specific grade or GPA requirements as conditions of admission, then your answer is clear cut.

If it lists something vague like “we expect you will maintain your academic performance in senior year”, then you will have some uncertainty. The usual forum chatter is that rescission is unlikely unless you earn a D or F grade, do not graduate high school, or commit a felony. However, it is possible that if a college has an overyield situation, it may choose to set a higher senior year GPA standard and rescind more “senioritis” admits to get out of the overyield situation.
