Find the equations page and keep it for handy reference. Depending on which Physics you're taking, 1 would need just the equations sheet for ridiculously easy problem solving while 2 would require you to have a foundation of electricity and it's inner-workings. Definitely continue doing as many practice problems as you can. Go over specific examples in the textbook that illustrate how to solve problems in the grand scheme of things, like initially setting up the problem and such.
