I never took calculus here, so I don’t really know about intro classes, but I’m the kind of person who speaks a lot in class. It’s math—sometimes all the equations flying around are tough to handle but just relax and keep it laid-back and math is fun. Make sure to ask questions in lectures even if they seem stupid. I can’t tell you how helpful a simple clarification is and usually someone else is confused about it, too. Make sure to start problem sets early and do work, son!
