I'll be starting my fourth year of my engineering degree. Up until now, I've always had as much fun as possible during my break, and just jumped in when the time came. Now, though, I'm wanting to prepare ahead of time. I will be taking difficult classes and I think it would be smart to do some prep. My ideas: Academic: -review calculus, linear algebra, and differential equations -review thermodynamics -review transport phenomena Lifestyle: -build a steady sleep and exercise routine -start a steady diet -abstain from drinking -give up the "addictive" time wasting activities Social: -focus on spending time with people with similar lifestyles -become more comfortable spending time alone ============== Do you guys do this stuff? What else should I be doing? I want to be as prepared as possible.
