Are you dissatisfied with your class XII marks? Despite your best effort, did you fare badly in the exam?
As a result, do you find you cannot apply for certain courses? What are the options available to you now? Should you go for a standard degree or look at a specialized diploma? Look at the National School of drama, but for that they would see some performance in theatrical groups. So try and participate in some professional performances.
There are various government-run film institutes. There is also Whistling Woods, and a few others in Mumbai. You might also look at joining dramatics clubs and stage groups to learn and practice your skills. Engineering is seeing a big boom in placements across India with IT companies recruiting thousands of engineers. Before you choose a college, first, look for history i.e., how old the college is etc. Second is the location. Most companies generally prefer city-based colleges for recruitment, though for very good colleges, location is not a constraint. After that check websites for more information. Finally, actually speak to students of that college. They will normally be honest with you. Ask for specific information, list of companies, how many were recruited, was it on campus or off campus recruitment etc.
