The midterm exams have now been corrected. Here you can find a detailed breakdown of the points, along with the grade that you would have obtained if this had been the final exam. Note that the midterm only enters as 40% in the final grade. If, for example, you received a week C now, you can still get an overall B with an 'average B' (or better) in the oral exam.
Let me know if anything is unclear about the point assignment -- but please make sure to take a look at the detailed grading instructions (and solutions) before.
