Guidelines for students who cannot follow the (Finnish language) lectures:

  • Read the chapters from the text book (required sections are mentioned in the exercises pages).
  • Do the weekly exercises to test that you have learned the material. Write your solutions on paper.
  • Participate to the small group session on thursday 12-14. If this time does not suite for you, contact the instructor.
  • Repeat this for five weeks and then prepare for the course exam.

Please start working at the same time when the lectures begin. If you wait until the first exercise is due, it will probably be too late to catch up.

Empty papers are full of space for knowledge.
