I would say a big no. Never go behind the brand name of a college but see the curriculum they have and what they are actually offering to students, the placement and package for the degree you want to pursue there. Don't trust college posters, banners or other marketing materials.
Try to get in touch with the students out their in the institution you are willing to pursue your studies via the social network, or have a visit to the campus and interact with them. All the best.

Doing MBA after BCA, according to me, is a good option because by pursuing MBA, you will be studying a lot about management and you already studied and gained sufficient knowledge about IT and Technology from BCA. So, as per my understanding, doing MBA is a good option. Rest is all upon you.

You can apply for BCA course through the college website. Pay for the application fee and send all the relevant documents to the college via speed post, include all the requirement documents along with application fee challan. The eligibility criteria is pass in all subjects in class 12th. They won't see any best of five. You must score pass marks in all the papers without supplementary. The selection process includes academic performance, skill assessment and personal interview. Hope this helps.

Do regular course, distance courses have no value.
