The marks you get with INGInious are not equal to the marks you'll get for the project.
You can download the project instructions here. The extractor executable can be downloaded here for the x86_64 architecture, or here for the Apple Silicon chip.
You must first register to a group on INGInious with your partner to be able to submit.
This task will test your fuzzer with a toy example containing a reduced number of bugs. After the deadline, your fuzzer will be tested on another extractor binary, containing more bugs.
Only your last submission will be taken into account.
Be aware that, to alleviate workload on the server, you are only allowed 4 submissions per hour. It is therefore strongly advised to test your code locally before submitting.
