<p>Is it wise to do a BS in ME and then an MS in AE? </p>
<p>That depends on your career goals. It’s not unwise. People do it frequently.</p>
<p>Agree with @boneh3ad. Some people even do the opposite.</p>
<p>@fractalmstr what do you mean by opposite?</p>
<p>He means go from aerospace engineering as an undergraduate to mechanical engineering as a graduate student.</p>
<p>@boneh3ad can I finish the ME graduate degree in two years?</p>
<p>@boneh3ad which is better BS in AE and MS in ME, or BS in ME and MS in AE</p>
<p>There is no “better” here. What are your career goals? That should determine which is “better for you.”</p>
<p>And you could finish either graduate degree in two years.</p>
