From Engineering360: Letter to an Engineering Student

You will be required to take some physics, chemistry and biology courses indeed.

Understanding the concept is truly important. Most students will think, just I am sure I did, that "I will never use this stuff ever". However, understanding is the key to later learning. I can't recall how many times in my early employment years I had to refer back to all these basics, relearn them and consequently remember them as I could now see "why", as they were necessary for the jobs I was doing.

Very encouraging letter. Hopefully it will guide some.
