<p>I am a current freshman and had a class with lab during the first block. Classes meet everyday 9-12 and our lab was usually a couple fo hours in the afternoon (2-4) a couple of times a week. One of my next classes is astronomy and lab is 1-3 in the morning. </p>
<p>Missing a day isn’t too big a deal, but since classes are so small it’s best to let professor know in advance or soon therafter because thee aren’t too many excuses except illness to miss since you technically have no other committments 9-12am. A couple of kids I know had to drop a block because they were sick for a week.</p>
