Hello omarselim
Yes, the Activities module is related to Gradebook Grades via its Eligibility features.
To test it:
1. Enter Gradebook Grades as a Teacher.
2. Then, access the Activities > Enter Eligibility program.
3. Here you have a link to autofill the form based on student's grade
4. Codes are "Passing", "Borderline", "Failing", "Incomplete".
That is, a student is given access to activities (or extracurricular activities) based on their assignment grades of the quarter to date (an option can be checked for cumulative grades).
Eligibility is taken once a week, you can control the entry times as an admin via the same Entry Times program.
Finally, when consulting the Activities > Student Screen, you will have both the activities list, and the eligibility results for the selected week / timeframe.
