Oh that sounds really cool! Do you do much designing of things yourself at the moment? Teaching sounds amazing! That is actually what I wanted to do when I finished school! Alas I didn't get into the uni I wanted and then I started a course in Early Childhood at TAFE, Then I had a bad injury, did a business admin course, and had a bit of work but it didn't work out, and I found out I liked the finance side better, so that's where I'm at now, I'm currently about half way through a cert 4 in Accounting I'm loving it!
I found that knowing the basis for essays is good, it has helped me write job applications, as I find my better applications and ones where I've been called in for interviews follow a similar kind of structure. And you'll need to know essays for uni. They are a necessary evil unfortunately.
