<p>Hey, is the lecture that's on tuesdays for Physics 1A an actual lecture or a demonstration? The general catalog says there's an hour of demonstration. Do you miss out on that much if you can't go to it? I have a schedule conflict that's a little messy.. thanks!</p>
<p>When i took it last quarter… it was a lecture. so yes you should go. the professor just had random demos throughout the course</p>
<p>For my Physics 1A/1B classes, it was a lecture like any other, so missing Tuesday wouldn’t really be any different from missing Monday. So, basically what peebeeandjay said.</p>
