Requirements & Grading

For successful class completion, students must complete a series of assignments (aka Zapocet) and the exam/bonus assignment.

  • You need 30 points (out of 50) from the assignments to get the Zápočet.
  • Surplus over 40 points, will improve your final grade after passing the exam/bonus assignment(up to 10 points).
  • The Bonus assignment is a special assignment given over Christmas which allows you to skip the exam if completed.
  • Both bonus assignment and exam include theoretical AND practical tasks
  • Extra points can be awarded for:
    • Special Award for Services to the School - If you do something notable and we like it, you can get points!
    • Participation in the Side quest.

The final grade is computed using the standard CTU grading scale as follows:

Exam score + surplus from assignments + any additional points = Total points

GradeABCDEF
Total points90+81-8970-7960-6950-59<50

Examples

You get 50 points in the assignments. You can take 10 points to the exam. In the exam, you get 85 points. You end up with a total of 85 + 10 = 95 points, which is grade A
You get 41 points in the assignments. You can take 1 point to the exam. In the exam you get 59 points you end up with a total of 59 + 1 = 60 which is grade D
You get 35 points in the assignments. You get Zapocet and can take the exam but without any bonus points. The points you score in the exam define your grade.

FAQ

How do I pass the course?
You must collect at least 30 points from the assignments to get an Assessment (Zapocet). After that you need to get at least 50 points from the exam to pass the course.

I have scored above 40 points from the assignments, how does it benefit me?

Anything above 40 points is added to your exam score after passing it. For example if you reach 46 points from the semester and 75 from the exam, your final score is 75 + 6 = 81, which is equal to grade 'B'

What are the due dates? Is there a penalty for submitting my work after the due date?

Each assignment has a hard deadline. Submission is not possible after the deadline.

Can I re-submit an assignment?

Yes, but in some cases, there are limits on the flag submission so we prevent brute-forcing.

Do I have to submit all assignments?

No, you don't have to submit everything as long as the number of points exceeds 30.

Can I submit the bonus assignment and still take the exam?

Yes, you can take the exam after submitting the bonus assignment. If you earn more points in the exam, your grade will be improved.
