<p>My school’s quarter system is exactly like a semester system but broken up into three chunks instead of just two. </p>
<p>Labs (like Chem, Biology, etc), music ensembles, and private lessons are generally worth 1 hour. A select few main (our Intro Engineering, some Chemistry, etc) and various other courses are worth 2 hours. Most main courses (like Math, Science, Business, etc) are worth 3 hours.</p>
<p>Oh, and the maximum hours a student can take here during a quarter without special permission is 12.</p>
<p>As for how long they meet, labs are around 4 hours long and meet once a week, 2 hour courses meet twice for an hour and fifteen minutes, and 3 hour courses either meet three times a week for an hour and fifteen minutes or twice a week for an hour and fifty minutes. </p>
<p>I hope it helps a little to see another perspective/system.</p>
