-## Examination
+Welcome to the 2019 run of the TN2844 course *Vaste Stof Fysica*.
 
-* During the course you will need to take 3 compulsory minitests.
-* Two of the best minitest results will each count for 10% of the grade.
-* The final exam counts for the remaining 80% of the grade.
+## Schedule
 
-We count points for each test from 0 to 100.
-For example if your scores for the minitests are `68`, `89`, and `56`, and the exam score is `75`, you get `68/10 + 89/10 + 75 * 0.8 = 75.7` points, and a grade of `7.5`.
