You will be kicked out of the major, and will not be able to sign up for any other major that requires that class. The College's Progression Requirements state:
A student cannot repeat courses from the College of Engineering and Computing in which they earned a grade of C or better. In addition, a student cannot repeat any course from the College a second time. For this purpose, withdrawal from a course with a grade of W is not regarded as enrollment in that course. A student that does not satisfactorily complete a degree-required College course within two attempts must change major or transfer out of the College of Engineering and Computing.
So, if you are taking a CSCE course for the second time, make sure you get a C or better.
