<p>No limit, as long as your dean gives you permission. I have seen people taking 25 credits. I personally have been taking 19 over last year. double major across comm school and CLAS with 2 concentrations and wanting to get a CPA require me to do that… but I still got 4.0 for both semesters while holding a part time and doing research for a prof so overloading is doable. it just takes a lot more work.</p>
