Is it effective to answer questions one day before the end of Shu Hui's online class?

If the course is over, then asking questions will not increase your interaction score. Only when the course is not over can you increase your interaction score.

Therefore, I suggest that you must brush your scores to the right place in time when you watch online classes in the future, otherwise your grades may be affected.

In fact, there are not many interactive scores, so don't worry.
