Wisconsin does not give advanced placement for a “passing” score of 3 on AP calculus; a score of 4 is required to get advanced placement, according to https://www.admissions.wisc.edu/apply/freshman/apib.php . Here is the Wisconsin math placement algorithm: https://www.math.wisc.edu/undergraduate/math-placement-tech-algorithm-uw-madison .
Students with sufficient AP calculus scores to be allowed to take advanced placement at Wisconsin can try the old final exams of Math 221 and 222 to check their knowledge when deciding whether to take advanced placement: https://www.library.wisc.edu/math/services/course-reserves/ .
