One thing, that I actually learned this year, is don't underestimate the workload that you are going to be presented. The past 2 quarters at Cal Poly were not that much demanding and time consuming. However, once you start packing on core classes with major support classes, things start to get a bit iffy.
From my perspective, I have always enjoyed creating things or making things with a certain task at hand (FIRST

). However, understanding concepts and material does take a longer amount of time for me to consume.
Just know your limits when it comes to coursework and also be able to cut back on certain things to ensure that your education is not being hindered.
