I am not familiar with the grading system of your country but most of the colleges which offer PG programs don't care about your grades. It's more of an immigration gateway, let's just put it that way.
If you are really interested in getting on a master's program, its a whole different ballgame. you need to identify your research areas and then find a few schools you want to attend. You can connect with the professors by visiting the university website and share your research interests with them and seek guidance.
