<p>Double majors have more overlap, like psychology and sociology. Your engineering and philosophy idea would be a dual major because they don’t share as many requirements that overlap. Engineering has a lot of requirements, so it would not be as easy as some. I do know a young man who is majoring in engineering and minoring is sociology.</p>
<p>If you start with the idea of the dual major, you will be able to figure out how difficult it will be. You will also figure out whether you really want both majors. If you have some AP credit, that might help.</p>
