Hello Aspirant.

As you've scored 67 percentage in class 12th and as you know that you need atleast 75%( for general) aggregate in 12th to get college through JEE main examination and BITSAT. And you need 60% in each subject pcm to get admission into vit through VITEEE. Henceforth, if you're from general category it would be best for you to focus on COMEDK examination.

If you're from OBC/SC/ST category then focus on JEE main examination as for them NTA request 65% in 12th.

Best of luck

It will depend upon the preparation you have done for the examination and the eligibility criteria set for each of these test. For example in JEE main to get admission in IIT or nit you have to have 75% marks in pcm which you dont have. So you cant go into those. So check out each test eligibility criteria and prepare accordingly
