I made the mistake of trying to take College Algebra and Trig at the same time. I got a B in Algebra, (after 15 semester hours of remedial math classes) but at the 10-week point, I was finally getting the stuff from the first 5 weeks of the trig class. I got a 34% on the final exam, and that was one of my higher grades...
I'll take trig again, some day, but not when I'm taking ANYTHING else.
But all he really wants to do is play computer games!
