This was much more difficult. Peer grading was challenging.

nice course but it was really hard the Math Parth!

I​nitially, I was excited by the concept of this course: developing your own projects and having them graded by your peers. However, in practice, this tested my determination... There were quite some variables one could not necessarily control: time differences, differences in Excel settings like which decimal separator someone used, how many people were currently submitting their work for you grade and would also grade your work in turn.

I​n retrospect, I would have preferred this course to be structurally similar to the first two, which helped my coding immensly. Since I already do code projects in my everyday work, the approach of this course did not help me develop me skills further.

O​ne concrete tip for the organizers of this course, be it Coursera or Charlie: If one has to resubmit their work after initially failing, one should have to grade three peers once more, otherwise this system just doesn't work!

Course material was great, and continued to learn a lot in VBA. The peer grading process did not work very smoothly and was a general headache to deal with. Much preferred the way assignments worked in parts 1 and 2.
