tyeso ho bhane gmat, gre ko laagi halka hoina darro preparation garnu paryo

Are you still in the school? Maybe you can take few more credits to up your overall GPA?
I was going to advise the same thing as funtush said, depending upon what you want to pursue, study hard (like 3-6 months, 2 hrs/day) for GRE/GMAT. Sometimes GRE/GMAT score will help out bad GPAs.

Third option is to chose a school that will not heavily look upon your GPA. You have many options, you won't find the top schools but you at least will graduate.

Undergrad GPA is ONE among many other admission criteria in grad schools.  GRE/GMAT score(depends on your major), undergrad projects and / internships if you have any, personal statement, recommendation letters counts equally. These should be able to complement your low GPA. I don't see an issue here getting into a grad school (even with your GPA) however admission with funding at least in a mediocre school you might wanna take other factors into consideration and plan wisely. Good luck !
