Does Economics 1 cl in college include lots of math? How hard, or easy, is this cl?

Yes, there is math involved. There is a LOT of graphing things, so if you did well in the graphing portion of math cles, this is the most important part. There will be a smaller amount of algebra involved, using formulas like 2a + 5b = c. If you can do well with that level of math, then the intro Econ course will work fine for you. If not, you probably should do your math cles first and save econ for your sopre year.
