You can apply for grace marks & get the memos. If you apply for RV & then apply for grace marks [By using 4-2 semester memo] in such case JNTUH wont declare your RV results for your hallticket no. You can apply for grace marks only after you get the semester memo [Failed memo].
It does not reflect your carrier. Regarding star mark each & every student will get a star mark in memo [Irrespective of passed or failed as mentioned in the starting of this post]. So that not a big deal.
We know that we will get 2 star marks in CMM and I am asking you that do I get 3 star marks in CMM ? AND 1 star mark in 4-2 sem MEMO? If you are sure plz answer me and don't mine, if not plz confirm from the University and answer me..
Thank you in advance....
