Information and tentative plan for the exam

Dear all,

You can now find some information and a tentative plan for the exam:

https://github.uio.no/IN3130/h25/blob/main/exam-information.md

Note, that it is a tentative plan, meaning that we can compact the schedule of each day (move you time a bit) in event that students are not signed up for the exam. But you will not be moved to other days.
