<p>how good are the notes? especially for math classes? is everything the professor says written down (including test dates, etc)? or is it just what is written down on the board?</p>
<p>It depends on the class (I know, an unsatisfying answer).</p>
<p>If lecture for the class is useless (like some math lectures), the notes will be too. </p>
<p>The notes have an announcement section, where they have whatever announcements professors makes (test dates, study session times, what to bring to midterm, changes in office hours, etc). The notes are usually a combination of what is written on the board and what the professor says.</p>
