We have got submissions by 217 students. For each value x, the plot shows the cumulative number of students whose fastest submission runs in at most x seconds. Blue — graded solutions, submitted early (198 students). Black — graded solutions, submitted late (19 students). The black line indicates the threshold for full points, and the gray lines are other point thresholds.
Here the x axis is days since the course opened. Blue — when the students submitted their latest solution. Black — earlier correct solutions. The black line indicates the deadline for this task, and the gray lines are the starting and ending days of the course.
The plots are based on data loaded on 2022-08-08 at 09:00.
