<p>Unless an employer sees your transcript or you have specific clues they can use to identify your age, most employers won’t know whether it took you 4 vs. 5 years to graduate. As for employers, most probably won’t care. Now if it takes you 5+ years to get your degree, they might like an explanation, but they most likely won’t care if it takes you an extra semester or two to graduate.</p>
