19 Feb 2015, 17:59 UTCI thought it was only fair to inform prospective students that there would be a tiny bit of calculus and some physics. These enter in mostly in the Rockets and the Orbital Mechanics lessons. The calculus is very simple, like the integral of dm/m is ln(m). Physics is mostly at the level of Newton's laws of motion. Also, most of the lessons don't deal with this. So review simple Newtonian mechanics if you have time, but don't worry about the math and physics being too complex.
