<p>If you are not sure, start down the mechanical engineering track. It, ultimately, offers the most breadth in engineering and will, therefore, give you the most options down the line. Keep looking at the other more specialized areas. You may want to go in one of those directions later. As others have said, most of the classes in the first year or two are pretty much the same basic subject matter. The examples that they use may be different, that’s all.</p>
<p>This is the same advice I am giving my daughter, who is a freshman in “engineering, undecided”.</p>
