Some people are just much better organized. I studied physics at a pretty good school. A lot of my classmates were very smart and hard workings. We spend easily 8 hours a day doing problem sets. Then we had an exchange student who cam from France (from the Prepas system) and he was just so much more organized with his work. He would sit down and very carefully read the chapter, make sure he understood everything. Then work through each problem carefully and then spend the rest of the day relaxing. Till he was done he wouldn't get distracted, check his phone, shoot the shit classmates. Just a very focused mind.

Looking back at college it was easily 80% worrying about doing work and 20% actually doing it. With something like programming, knowing how to use a debugger, profiler and an IDE give you a huge leg up. Easily 95% of CS students never take the time to learn the tools b/c you have to do it on your own time - but you have other homework to stress out about.
