o General information

This course page will be updated pretty often, almost daily. So check it regularly, at least once a week during the course.

  • Course material will also be found in the course folder in room A412.

  • The news group for the course is hy.opiskelu.tktl.tili . It is meant mostly for the commucation between the students attending the course. It you want fast answers from the lecturer, use e-mail.

  • Slides used in the lectures (in Finnish) and problem sets for the exercises are also available in the web.

  • There is one course exam that gives maximum 50 points. To pass you have get at least 24 points from the exam.

  • Exercises are important part of the course. They are not compulsatory, but very very usefull. Active participation can give you up to 10 points. Also by writing small (5-10 pages) studies or summaries about subjects related to data communications or by giving short presentations you can get extra bonus up to 10 points.
  • The points from exercise and other activities activity are valid only in the course exam and in the separate exam in January .

  • To get points from the exercises you have to participate actively in the exercises. You have to do your homework and solve the given problems before coming to the exercise group. It not demanded that your answers are absolutely correct, it is enough that you try your best to solve the problems. In the beginning of the exercise sitting you mark in the around going list those problems you have solved. A mark in the list means that you are ready to present and explain your solution to the group.
  • Each mark in the list gives you one solved problem point (SPP). As there will be about 36 problems the maximum amount of SPPs will be about 36. About 3 SPP gives one exercise point and 30-33 SPP gives the maximum 10 exercise points. Other exercise points will be given linearly between those values.

  • To pass the course you have to get alltogether at least 30 points. And at least 24 points of these from the exam. This 30 points gives you the grade 1-/3. To get the best grade 3/3 you need 51 points.
