<p>If you get in the habit of limiting yourself to 12-13, you’re not going to graduate on time. 19 can be manageable, I’d say, although it greatly depends on what the classes are. I’d go fewer than 19 if something you’re taking relies on the class you’re struggling in now.</p>
<p>19 sounds like an overload. I think average is 12-16. I don’t think graduating on time should be your first priority if you can’t handle the load, so take it easy if you want to focus on good grades (but this would only apply if you pay by class and not by a set tuition). I would recommend staying at around 15 or take 12 credits if the classes are harder/more demanding. </p>
<p>I’ve taken both classes where one was once a week and once was twice a week. Go for once a week if getting skmething out of the class is not a priority (ie; a gen ed). Twice a week is better in terms of learning because in one week a lot can happen and I tend to forget important info or some assignments, but it was better schedule-wise to do other things.</p>
