I'll be taking these two classes together this fall (along with an intermediate college writing class and a one-hour-per-week mathematics computing lab). Am I biting off more than I can chew? I am getting an A- in precalculus, which I admit I only study the bare minimum and am about one or two correct answers from an A. Here are the descriptions of the two classes: Physics for Scientists and Engineers I: First semester of a two-semester sequence in calculus-based physics, primarily for students in science, math, computer science, and pre engineering. This semester covers topics in mechanics, including kinematics, Newton’s laws, and the conservation laws of energy, linear momentum, and angular momentum. Also covered are topics in gravity, fluid mechanics, waves, and thermodynamics. Class meets five hours per week in lecture/discussion format. One 3-hour lab per week. Calculus I: Limits, continuity, differentiation, integration. P.S. I am a 30 year-old freshman trying to find time to start a business or get a job at the same time. Maybe that's more than I can chew. Thanks for your input.
