You may be in a different situation than I was, but I personally wish I had read Study Hacks or some of Cal Newport's books when I was in your situation. Lots of clear, actionable advice for building a remarkable college career, no platitudes. Email him at author [at] calnewport.com if you have a specific question, he'll answer you (eventually).
