Pour faire fonctionner la récupération de l'avancement des étudiants avec google forms, il faut:

1. Create a new form by clicking "New" on https://drive.google.com
2. Name your form something memorable.
3. Your form should have only one question which should be a paragraph type question.
4. In the upper right corner of the form there should be three vertical white dots. Click on that icon and then click "Get pre-filled link." This will open a new window.
5. Dans le champs réponse tapez toto, puis cliquer sur "obtenir le lien" et copier le lien.
6. Paste the generated link into customTests.R where indicated, so that a string containing the link is assigned to the pre_fill_link variable in the function submit_log(). Enlever toto à la fin du lien

Pour décoder les réponses des étudiants:

1. Download the csv results from Google Forms.
2. Sourcer mon script mon_google_form_decode.R
3. Run mon_google_form_decode() and select the csv you downloaded.
4. google_form_decode() will return a data frame containing how each of your students performed on every question.
