Evaluation

Method(s) of evaluation

  • Oral examination
  • Written report

Oral examination

Written report

  • The evaluation of the practical work will be done on the basis of a series of assignments to be handed in during the term.
  • Oral exam without note, depending on the circumstances, exam can be done remotely using Teams.
VERY IMPORTANT!
In order to certify your regular and personal work, you are requested to use a version control tool such as GIT (preferably https://gitlab.ulb.be/) to record the progress of your practical work.
We ask that you DO NOT use generative AI to complete your practical work. This is considered bad practice and goes against the objective of learning by doing. In all cases, you will be assessed on your understanding of the code you submit.

Mark calculation method (including weighting of intermediary marks)

80% oral exam + 20% on the quality of Practice work
oral exam (2 questions without notes)

  • 1 theory question 50%
  • 1 problem based question 50%

Language(s) of evaluation

  • english
  • (if applicable french )
