Two school years ago I took 19 and 20 credits. Last fall I took 16 and worked 6 hours a week and had a crisis and in the Spring I took 15 credits while working 15 hours a week.
So, Laralula, I'm upping credits and work. I've also found that I'm somewhat the opposite of you when it comes to studying. For me, most of my assignments require more than an hour for reviewing a chapter or an assignment, so I feel more tempted to goof off. I also go to a small college, so for classes that aren't gen eds, there is typically only one section/time. All of my classes will interest me except the economics gen ed. 4 credits are tough with a lab too and 7 are "medium", 4 are "easy", and the last 3 credits, I've got no clue what to expect. They have reinstated our ability to do homework and study at one job. I do plan on getting all A's of some type. Once I get some money saved up for next semester/year and if its overwhelming I might just quit my 2nd job. I've "mapped" it out and it looks do-able, but there's still the online class and I'm horribly afraid of a crisis. I'm just overwhelmed looking at this trying to figure out if I will be overwhelmed. I wish there was a simple way to figure this out and to know before hand.
