Hey Diksha,

In order to calculate your marks from garde points in every subject you need to multiply it by 9.5. For example if you scored 8 CGPA in any particular subject say English you  need to multiply that by 9.5 in order to calculate your marks which will be 8*9.5 =76. Similarly you may calculate for rest of the subjects.

You this is still not clear do ask.

Good luck!
