As per the 4th amendment of CAS. There are only 3 point will get to you for National conference and it is not for publication, but presentation of paper. No marks for paper publication of paper in National conferences.
Yes, if you are invited for lecture, you will get additional 5 point. But question is that who will invite you. Because everybody inviting university librarian, deputy librarian, member of board of studies and so on. It is a time to change the style of National conferences. If you are going to National conferences for collecting point, it will be wastage of money, time and valuable research paper.
