I graduated in 1985 with a BS in Design Engineering Technology (basically a CAD centric ME). I have worked most of my career with engineering tools like CAD, PDM and PLM. I have raised 4 children and helped them all with their math and science homework. I also lived for a couple years in Central America where I became fluent in Spanish. To augment what I learned while living there, I also took 3rd Year Grammar and Intro to Spanish Literature. So I also helped my kids with their Spanish homework. The great thing about knowing Spanish is that you can use it almost every day.
