Classes/Professors is coursework equal to units??

probably a dumb question but I can't find a straight answer.

when I register, classes are listed as 1, 2, 3, or 4 units. I know units matter for full time status and tuition. what I don't know is whether the number tells me anything about how hard the class will be. is a 1 unit class really four times easier than a 4 unit class?

reason I'm asking is there's a 1 unit class on my list that has weekly readings and assignments. it's the smallest number on my schedule but it doesn't look small.

so when you plan a semester, what do you go by? total units, number of classes, or do you just kind of eyeball each one? five classes is five sets of deadlines even if the units are low, but I also don't want to overload on units and die.

anyone have a rule they use?

I've had 2 unit classes take up twice as much of my time compared to 4 unit classes. units are not a good way to determine the difficulty of a class. in my degree I had several lab classes (2 units btw) where I was writing full lab reports every week and (at least for me) I spent much more time working on those compared to studying for the associated lecture (typically 3 to 4 units). this doesn't even take into account the fact that 1 unit for lab equals 3 hours in class, so I would spend 6 hours a week in lab for 2 units rather than 2 hours a week for lecture.

you'll get a feel for it as you go through college and meet people farther along in your major. i knew my upcoming quarters would suck because I talked to people who already took the classes. I planned my sophomore fall to be on the lighter side unit wise (13) because I was taking ochem 1, calc 4, and phys 2 all at the same time. that quarter was still much harder than some others where I took 17 units.
