It is not necessary to attend all the smart sessions. Instead, the requirement is to accumulate a total of 1000 points within the duration of your internship. This means that you have flexibility in choosing which sessions to attend, as long as you reach the required point threshold by the end of your internship.
The point system allows interns to have some autonomy in managing their schedule and attending the smart sessions that align with their interests, availability, or areas of focus. This flexibility can be beneficial for interns to balance their workload, prioritize tasks, or accommodate other commitments while still actively participating in the smart sessions.
