    It's ok.
    Just continue attending the rest of the classes.

    Attendance criteria: be present for 80% of the batch ( 10 of 12 classes )

    There is a tick mark on each class date.
    that confirms you attended the session i.e at least 80% of the duration of the session.

    Nope. Attendance will not be marked.

    Attendance criteria :

    1) Be present for at least 80 % of a single session i.e If the session was for 180 minutes, you should be present for at least 144 minutes in total.
    Only then, the tick mark on the class will appear on the date you have attended the session. Check -> LMS ->Classes tab.

    2) Be present for 80% of a "single batch" i.e 8 of 10 classes ( 8 tick marks out of 10 "or" 7 out of 8 classes )

    0 classes attended will reflect as 1 class(es) attended once you satisfy this.
    Hope this clarifies.

    Hi Sayan, can u plz explain the following function for removing multiple instances while preserving the sequence:

    #I am not able to understand return part

    def unique(sequence):
    seen = set()
    return [x for x in sequence if not (x in seen or seen.add(x))]


    Input: unique([5,1,2,6,4,6,8,1,3,6,1])
    output: [5, 1, 2, 6, 4, 8, 3]
