<p>is this possible at carnegie mellon?</p>
<p>and is the a minimum time one has to stay at the university?</p>
<p>Not really sure what your question is, but at SCS for example if you can stay for a fifth year and get an MS. Depending on how much AP or other credit you have coming into the university, the fifth year may not actually be a fifth year. The university requires four semesters or 180 units at a minimum, but some departments/schools may require more. If you go to [2008-2010</a> Undergraduate Catalog](<a href=“2024-2025 Undergraduate Catalog < Carnegie Mellon University”>2024-2025 Undergraduate Catalog < Carnegie Mellon University) you can find the answers to most of these questions.</p>
<p>One of my friends managed to do a BS/MS in Materials Science in four years with almost no AP credit. I could have gotten a MS if I had planned ahead a little more and not graduated early.</p>
<p>The standard timeframe is you start your MS in your fourth year and then graduate your fifth year with your BS and MS at the same time.</p>
