After throwing away the idea of taking notes and concentrating on understanding exactly what was being said 100% of time, everything got easier and if I remember right, my marks even improved. And the best part: less stress.
I very much recommend never taking notes. If you concentrate and understand exactly what is going on, you don't need notes. You can look up whatever little facts you may need later in the textbook or online. If you understand the concepts, there really are no notes that need to be taken.
