Hello Vinesh,
Of course the CAT score is given the most preference in the admission process. The percentage of it considered in the total process, however differs from college to college. Some universities have the break-up like this: 60% CAT score and 40% GD/PI.
This distribution differs, but always the CAT score will have the highest percentage.
The 'graduation score' is given the lowest preference in almost all the universities or sometimes it isn't even considered, because nowadays GD/PI have become more important in the admission process.
All the best.
