Putting in stuff that is irrevelant to major?

<p>Example: </p>

<p>I want to get into an mech/electrical engineering program, would it look good, bad, or too random, to mention the fact that... say, I was CompTIA certified at 15, or a certified welder at 16? Just ignore it and write something else? Mention it? </p>

<p>Thanks guies!</p>

<p>btw, I mean for like a supplement portion of an essay. Honestly, to explain my "lack" of EC's and hours.</p>
