MCQ

This year, a compulsary MCQ will be taken by every student the lesson following the deadline of each project. The objective is simply to detect any form of plagiarism (copy the code of someone else, ask someone else to do your project, or even ChatGPT). Therefore, the MCQ should be very simple for anyone who has done the project. Some questions will be about the concepts seen in the project, but some questions could also be of the kind “Was there a challenge where you had to do X?”.

Date

The MCQ for the first project will be held Wednesday, 9th April 2025 during the lesson. The exact time and duration will be announced later.

Quotation system

Questions generally have between 3 and 5 propositions. The number of correct propositions can vary from 1 to the total number of propositions - 1. You can choose to select any number of propositions for each question.

For each proposition that you select, you will get a number of points (positive or negative). For each proposition that you do not select, you will get 0 points.

The number of points you get is computed as follows:

  • If you select a correct proposition, you get 1 point divided by the total number of correct propositions of the question.

  • If you select an incorrect proposition, you get -1 point divided by the total number of incorrect propositions of the question.

Examples

  • What is the capital of France?

    • Paris

    • London

    • Berlin

    • Madrid

    There is only one correct proposition (Paris) and 3 incorrect propositions.

    Someone choosing “Paris” and “London” would get 0.66 points for this question:

    • Paris selected and correct ✅ -> +1/1

    • London selected and incorrect ❌ -> -1/3

    • Berlin not selected ⚪ -> +0

    • Madrid not selected ⚪ -> +0

  • Which of these is/are prodigious computer scientist(s)?

    • Alan Turing

    • Isaac Newton

    • Elon Musk

    • Laurent Mathy

    The correct answers are obviously “Alan Turing” and “Laurent Mathy”.

    Someone choosing “Isaac Newton” and “Elon Musk” would get -1 point for this question since these are the incorrect propositions -> -1/2 - 1/2 = -1.

    Choosing “Laurent Mathy” would get 0.5 point for this question since this is one of the two correct propositions -> +1/2.

Tip

Last year, the same quotation system was used for the MCQ before the exam. Some students tended to not answer the questions they were not sure about. This is not necessarily a good strategy since the expected value of answering at random is not negative (it is 0).
