pls reply its very urgent

For old students, conversion is not automatic until the maximum permissible no. of attempts have ceased. Therefore, you will have to opt for new course, lest only the old course is applicale to you.

HI Swathi, it is not compulsory to convert from old to new course until after Nov. 2020, which is the last attempt for the old course. This notification is for those who have opted to convert to new course.

So you can give 2nd group in May '18 under old course itself.
