Dear Mr Biswas,
As informed by Matt, it is not required to complete the module again, if it has been already completed during the basic course. However if you desire you can again do it again to improve the score and also to revisit the content.
Unfortunately, the previous score for the NWA developed modules will not be reflected in the current grade book. This is because in the database, there is no link between the grade book of this course and the grade book of basic course. However for the COMET developed models modules, the previous scores can be imported in the current grade book, so the previous scores are also visible.
Though it is really not required to take the module again, my advice would be to go through it once, if that is not a major issue for you. Otherwise you can inform us your previous score of this module and we will the update the gradebook manually.
Best wishes,
Dattakumar
