If I am studying engineering in CALS, and I want to switch to a major offered within the College of Engineering, by which semester do I need to switch?

 

A student should apply no later than the end of the fifth semester so that he/she can meet residency requirements. However, applying sooner is better so that the student has access to both a faculty advisor in their major and the department communications. Additionally, a student may fail to meet good academic standing if he/she is taking a significant number of courses for a different major and not making progress within his/her current major and original college.
