Date of the 2nd exam: The re-exams will take place on the 11th and 12th of March in room 2.074. Please contact Clemens Rösner to schedule the time of your exam.
Things that are NOT relevant for the exam: Chapter 2.7 (outliers) will not be discussed in the oral exams. The same is true for proofs that were deferred to the tutorials, and tutorial questions. These are there to improve the general understanding of the material, but they will not be discussed in the oral exams.
Exams: The exams are oral exams. We offer times for oral exams on the 4th, 6th and 8th of February. After enrolling for the exam in BASIS, please contact Christiane Andrade to schedule the time of your exam.
Lecture Notes: The lecture notes have last been updated on the 25th of February and cover the whole lecture!
