There are many courses that you can pursue after your 12th class but that will depend on what Aptitude, Interest, Personality and skills. You are better aware of what your strengths and weakness are and what long term goals you have set for yourself. It would be better that you take your career decisions keeping in mind all these things.
You can go for B.Sc courses, B.Com, BA courses, BBA, BCA, Mass Communication, Hotel Management, Designing etc…. You can go for any of them depending on your choice of career.
I would have been in a better position to tell this to you if I knew what stream you have taken in your class 12th.
You can write back if you have any further doubts.
You can also take the help of the Psychometric Career Assessment that MeraCareerGuide offers for students to take better and right career decisions.
