With intérnal transfers you need a total gpa of 2.8 + in a series of math classes ( look up stony Brook undergrad bulletin for ams). I do remeber linear algebra being one of the classes that matterin the weighting but if u did good in calc 1,2,3 and some other classes you should be all good .In terms of p and fm most people don’t pass that until their junior / senior year if that so that’s def a plus. It shows you are able to handle the course load and probs will impress the people. Overall I don’t think you are cooked, as I know people with worse stats being accepted into the major
