<p>At that point it really entirely depends on what your own strengths and weaknesses are. Engineering might appear easy but feel tedious, you might really be just better at conceptualizing abstract notions than working with concrete things, etc. </p>
<p>So it’s hard to say, but usually, the first year curriculum for pure and applied math is pretty much the same (I’m not too sure about stats majors but it should be as well), so if you’re thinking of heading for math rather than engineering you will have the time to discover which branch interests you more.</p>
