Do not describe each illustration or example. Use abbreviations wherever possible. Trying to outline takes unnecessary time and effort. Skip lines between major ideas, thoughts or concepts. Listen as well as write.
Instructors have individual lecture, discussion and questioning styles.
Tune in to them. Don't become sidetracked by an idea with which you agree or disagree. Keep paying attention and write. Do not try to write everything being said. Pay special attention to introductions, conclusions, repeated phrases, repetitions of ideas in other words, comparisons and contrasts, and lengthy elaborations.
