I take notes in class but they are really messy (as are class-taken notes by definition) so I couldn't study straight from them (though, I still put them in the binder). Before the test comes, so some time after covering the material, I type this notes into the computer in a very structured, organised way. I use bullet point, bold font, tables (A LOT of tables) with things like date/name/cause/what happened/what was the effect etc. It makes my notes very organised, structured and chronological and extremely easy to use. I NEVER write in plain text - it's ever table or bullet points (and I highlight/bold names and words that are the key ones). It's the best method I've used so far because it's dead easy to revise from them - you can find the thing you're looking for in a second.
When I was in middle school, I used to do it all in hand, using various coloured pens and highlighters. It can also be a good idea, really, if you're this type of person who likes to have everything easily distinguishable through using colours.
Also, when I revise, I walk around a room, waving my notes in my hand (I have a tendency to over-gesticulate) and tell myself a story. I just tell history as if I was telling someone about the plot from a book I've read. It all becomes a lot more interesting if you put it this way - and it's not that time consuming. It would work if you're more of this person who has to hear rather than see.
