You've got a good score.. There are so many colleges you can try. Welingkar sounds like a pretty good college.. heard that the college has some great specialisations to offer and the industry exposure is great. The admissions are open. You can apply online too.. All the best.. :)
Since, you have CAT scores, first find out the cut-off marks of the colleges you wish to apply at and make a list of the colleges you are eligible. Then, you can do an assessment of which college is the best of the lot.
