Skimmed the posts. BA or BS. It depends on the school. Your child needs to check the course requirements at each school being considered. I got a BA in Chemistry with Honors because I chose to- met requirements for both BA and BS. The major’s requirements were the same but the breadth requirements differed- science, humanities, social science and humanities in L&S at UW-Madison. Other schools may only offer a BS or a BA depending on the major or have different credits in the major.
Don’t worry about the degree. Focus on comparing required and available courses related to the proposed major.
