Since the Fall of 2014, I've taught calculus to students enrolled in 16 sections of Calculus I, II, or III (excluding sections forced online by the pandemic). Each of those classes has followed a similar pattern with three exams during the term and a final exam. I compute grades after each exam to let everyone know exactly where they stand. The visualization below shows how those flow throughout the semester. If you hover over the B under Grade 1, for example, you'll find that students had earned a B after the first exam and that of those students went on to earn an A for their final grade, together with links illustrating how the grades flowed along the way.
