I am going to be a freshman in college and I intend to major in astrophysics. This past year I took AP calculus AB, and I got an A and I believe I did well on the AP test (results haven't come back yet though). This morning I took my school's math placement test, and I was placed into multivariable calculus (Math 221). I had expected to place into calculus 2 (Math 122). Do you think I am prepared for multivariable calculus without having first taken calc BC (or college calc 2)? Any advice/guidance would be greatly appreciated.
