Revoked from UW-Madison?

So I was accepted into UW-Madison because of average grades in hard classes, being a Wisconsin resident, and admitted into the CeO program; a program in which is for students who are the first generation in their family to go to college, and low-income.

However, my second semester, I am suffering from a D+ in Pre-Calc honors. Math has never been my strong suit, and I am super worried that I will be revoked from the University.

My current grades are:

AP Government: A
AP Language: A-
AP Statistics: B+
Microbiology: A-
Pre-Calc Honors: D+
Painting: A
Humanities B: A
Creative Writing: A

How many kids do you guys think get revoked every year from UW, and how bad do your grades have to be for this occurance to happen?

The word is rescinded not revoked, and rumor has it that an offer of admission is not revoked unless a student has at least multiple (2 or more) grades of D and/or F.

D D
F F
D F

You may also want to prepare for the math placement test with that low grade to perhaps avoid taking a class you would rather not need to take.
