<p>It depends if the intro courses provide insight into the distinction between the two (or rather, if it provides any insight into BME at all; usually it just covers the more major/common fields). It’ll definitely show you if ChE is for you, though.</p>
<p>Again, it depends where you go and the BME program on whether BME or ChE is harder. A great BME program is going to be VERY difficult because as I said earlier, there’s just so much you have to learn and understand to perform it. However, most undergrad BME programs aren’t great - you become more of a mediocre jack of all trades. Then, lastly as you pointed out, it depends on the person. In engineering, everything depends on the person. Electrical engineering could be what you consider the hardest engineering discipline and mechanical the easiest, but maybe that’s just cause you visualize things very easily and are better at conceptualizing tangible concepts (or the vice versa, maybe you’re horrible at conceptualizing and visualizing, but are great with strict computation and mathematical theories and therefore enjoy electrical).</p>
<p>I’ll start off with what’s best: ME. Mechanical Engineering would be the BEST field for you to go into to prepare for BME. ME would provide the best general foundation and allow you to specialize with great engineering skills already intact. I would not recommend ChE–>BME, but I won’t argue against it because that’s the exact route I was going to take despite my acknowledgment that it was not the optimum pathway.</p>
