Last semester, I had a PPL ground school class at my community college that I signed up for. However, that class was in the late afternoon (4pm to 5:15pm). When I looked at other classes such as the CPL ground school class, it was from like 6pm to 9pm or something. The aerodynamics class is from 4pm to 5:40pm. So is it true that aviation classes are evening classes or is that only true in my community college? Thoughts?
