Also one bit of advice: try not to get too fixated by one particular facet of your course.
In the real world, Kirchhoffs' laws become common sense, and only very rarely does an engineer need to get pen and paper out to solve a Kirchhoff problem in the classical way. When I do, I don't even think Kirchoff, most real world examples tend to be quite simple and straight forward, not the comtrived examples all too often presented in class.
Not electronics related, but a few years ago while revising for an exam (meteorology for pilots FWIW) I found myself becoming fixated on two particular points, and spent days trying to understand. In the end I never understood those issues fully, but I still achieved 100% in the exam, the first time in my life that's ever happened.
