Hello everyone, I learn hard but I am not scoring much in GK Please suggest me how to score good marks in GK.

Read GK as a hobby, not for exam then you surely got good marks in GK.

Study more, party less.

Study, study, study, and when you're done, study some more. If you're having trouble understanding what you're learning talk to your teacher and ask for help, or ask someone else in your class that's getting good marks to study with you.
