Please contact the AM-SciML advisor, Prof. Eduardo Martin-Martinez, at amachugr@uwaterloo.ca to submit the relevant form. Math students typically declare their major by their 2A term, but you can switch into AM-SciML at any time after that as well. There is no selection process, and tuition is the same as for other Math majors. (Note that CS and DS have higher tuition, and many CS-major courses are only open to CS and DS students.) The AM-SciML program has substantial flexibility to facilitate combination as a double major with most other majors in the Math Faculty (exceptions are DS and CM).
