My mark after the exam ...

1. Exam will be marked from 0 to 10 (being 10 the best mark possible).
2. Attendance is already marked as a value from 0 to 1 (expressed as a %).
3. Assignments have been marked too (0 to 2).

First term mark (again from 0 to 10) we'll be calculated as:

1st-term = attendance + (9-assignments)*exam/10 + assignments

Same process will hold for the second term. Course mark will be obtained by averaging both terms. There is not a minimum average you need to obtain on each term, but course average needs to be equal or higher than 5 points to pass the course.
