CBSE 12th

Yes, you can do a postgraduate course in Virtual and Augmented Reality without mathematics in 12th. However, you need to graduate in related subjects. You can do postgraduate courses in VR/AR/XR from the following colleges:
1. Alagappa University of Karaikudi: At this college, a Post Graduate Diploma in Virtual and Augmented Reality is available. The eligibility criteria are graduation with mathematics as one of the subjects. You may apply if you have a degree in any of the following: B.Voc. B.Sc. BCA B.Tech in Computer Science or Information Technology etc.
2. Srinivas University: This university offers an MCA in Emerging Technologies (AI, AR, VR, and IoT), as well as an M.Tech in Artificial Intelligence and VR. You will need to have graduated in related subjects such as BCA or B.Tech to be eligible.
3. Alternatively, you may also take an online MCA course in AR & VR from Amity University of Noida. Therefore, your 12th grade subject won't matter if you have graduated in a related subject.

Selecting the right graduation course after class 12th board is one of the most the toughest situation for students. If you are willing to do an MBA, then BBA will be the better option as it will help you build a solid foundation and develop your basics which will help you in your MBA. But, in reality it hardly makes any difference whether you do B.Com or BBA. You won't be at a loss if you do B.Com. Only if you are interested to become a Chartered Accountant, CS or CFA then B.Com will be a better option for you. Even if you do BBA you can still pursue the above courses but then things will be comparatively tougher. BBA or Bachelor of Business Administration focuses on the studies related to management. The course equips the students with managerial skills, marketing knowledge and related expertise required to get a job in some of the leading organizations. If I talk about B.Com. Or Bachelors of Commerce, it opens the opportunity for the students to get a hold on accountancy, banking, retailing, taxation, media communication etc. Both courses are good in their own ways. You can go through the above mention points and think about the area of interest. Analyze the field that will bring out the best in you. Below are some of the best Private Universities:-
BITS Pilani, ICT Mumbai, Mumbai. VIT Vellore, Vellore. Thapar Institute of Engineering and Technology - [TIET], Patiala. ITER Bhubaneswar, Bhubaneswar. LDCE Ahmedabad - LD College of Engineering. Geeta University, Panipat.

You have not mentioned from which background you belongs to. If you are from PCM, I will suggest you to do B.Tech CSE. The way technology is growing and impacting our life CSE has a lot of scope and is a better option. Every organisation or company requires to be present digitally, be it banks, hospitals, education, or railways. Computer Science and Information Technology are one of the most evergreen professions and will continue to rise in the years to come. In CSE field nowadays the field expanded so much that you have many options to choose your career in the CSE itself. Some of the famous fields in the CSE branch is Artificial intelligence, Machine Learning, Android Development, Automation, Data Science and much more you can say. The B.Tech degree in Computer Science and Engineering is focused on providing foundational knowledge and skills to the students. This includes knowledge of core subjects as well as introductory content for advanced areas. Students learn such skills as programming, communication skills, presentation skills, teamwork, and project development, which are aimed at producing a lifelong self-learner and a good individual with a team working ability. However, the degree lacks in imparting education related to ethics and morality. When it comes to choosing the best university for engineering, IIT becomes the first preference but IIT is not just the only option. Few of the other leading options for engineering are:
National Institute of Engineering
Thapar University
UPES Dehradun
Geeta University, Panipat
College of Engineering, Pune
Symbiosis Engineering College
Delhi College of Engineering.
