Rewording material in my own words is extremely important to my comprehension. Practice tests are great.
I actually really hate lectures. I have great intentions to watch TED talks and never do, because watching somebody talk drives me mad. I also don't really take notes, or not very good ones. I would be that person in work meetings with three lines on the page while everybody elese dutifully scribbled pages.
I love to read, because I can skim, rewind, etc at my own pace. I did highlight very extensively in college, laregly to keep myself from skimming too much/too fast, which is a bad habit. Today, I highlight the studies I read for work, but do so much more discriminatingly--I am intentionally looking for key points. This helps me organize my thinking.
