<p>You take 2 terms of frosh hums, and then you really should take a hum 3rd turn as well (you need to make progress towards the requirements for graduation). Right now, I wouldn’t worry about it- by the time 3rd term rolls around, you’ll know what you need to do.</p>

The schedule stuff you see is all recommended- there are no classes you are <em>required</em> to take. However, they’re usually pretty good recommendations- you will probably end up taking 27 units of hum frosh year.</p>
<p>The numbers after each course (1-3-5) have to do with how many hours per week the course takes. The first number is lecture, the second is time in lab, and the third is approximate time to complete the homework (which is usually not very accurate). Add the three numbers together, and you get the number of units the class is (so this example would be 9 units)</p>
