OS exam

The first exam date (presentation) is on Friday, June 9, 2023 and starts at 14:00. See below.

As discussed at the lectures, the exam consists of two parts and provides different possible tracks. Also, we provide a bonus track to equivalate (equate) the exam in a manner related to the work you have done at the lab (see section B, below).

All students must choose the type of exam by filling in this form on Campus Virtual until June 5th, 2023.

A. The standard exam consists of two parts:

  • Part 1. Written exam, as a set of assignments that must be done in a limited time interval during the exam day. They will be:
    • a) A mandatory quiz consisting of 13-15 random multiple choice questions. The quiz must be filled in in 15 minutes. The maximum grade provided by the quiz alone is 7. Each question may have multiple valid answers, and the grade for that question is proportional to the number of correct answers. Selecting a wrong answer voids the respective question regardless of the other chosen answers.
    • b) An optional assignment consisting of developing a C program in a similar style with what you have explored at the lab. The program will have to be written from scratch during a limited time, and it must work as described in its specification. Programs with errors or which do not compile will not be taken into consideration. This will provide the additional maximum 3 points for a total grade of maximum 10.
  • Part 2. Oral exam, consisting of direct questions from the examiner to the student, in an interview style. This part will only be activated when necessary, at the examiner's choice, to clarify possible issues observed at the written part. Students will be asked to participate at a further date, and failing to do so will end up with failing the exam.

B. As an exception, this semester students can choose to equivalate (equate) their Exam with their Lab assignment grade (the project done during the semester) if that grade is equal with or higher than 5. For this purpose, they must fill in the form linked above with the proper choice. Once the equivalation is chosen, it will be valid for ALL exam dates (presentations) and cannot be changed after the first one. Important: students that choose this format implicitly agree, by choosing this option, that the equivalent grade is the final one for the exam, and that no change is possible at any other exam dates (presentations).

Timings and intervals for the first exam date

The exam starts at 14:00, on Friday, June 9, 2023 as follows:

  • the quiz (13-15 multiple choice questions) will be available between 14:00 and 14:45, and must be filled in in 15 minutes. At the cut-out time (14:45) the quiz will be closed regardless of when you started it so make sure you connect in time.
  • the optional assignment (the development of a C program) will start at 15:00 and must be submitted in at most 60 minutes. The cut-out time is 16:15, at which the assignment will be closed regardless of the time when you started it.

The assignment and quiz will be available on the OS Campus Virtual page, in the Exam section.
