BCA

Yes, you can. The minimum eligibility requirement for CPL is just class 12th. You should have passed class 12th with PCM (50% marks). For becoming a commercial pilot, there is a specific eligibility criteria, which you should first be aware of. This is decided on what subjects have you taken in class 12th. It requires PCM to be a pilot and, even if you have not opted for the same, then you can appear separately for these subjects and become eligible.
Further, you should be aware that you are medically fit to be a pilot, so I would suggest you to visit: http://www.dgca.nic.in/medical/medical-ind.htm and go to the class 2nd examiners tab to find out doctors who will examine you for initial fitness. You can visit any doctorate from the list as per your convenience. Once you are done with Class 2nd medical, find out a suitable flying club for you as per your convenience. You can fly in India or abroad. I would suggest you fly in India. Besides finding the club, be aware that you will have to appear for:
1. Air Navigation
2. Aviation Meteorology
3. Air Regulations
4. Aviation Technical
5. Aircraft Specific
6. Radio Telephony
Here, 1-5 are conducted by DGCA and 6 is conducted by WPC. Prepare for these subjects and appear, as exams are conducted every quarterly. For preparation, flying club will help you or there are private instructors available in metro cities as well. You will fly for 200Hrs + Clear DGCA and WPC exams + Clear Class 1st medical, then you shall get your CPL. The next license is ATPL, which you shall be able to apply for once. You will then have to probably fund or self-sponsor your type rating on whatever fleet you are selected in an airline. Then, you finally get a job as a pilot. I hope the process is well explained to you. CPL is an expensive affair. It might cost you around Rs. 18-20 Lacs for flying + DGCA exams Rs. 500/- each exam + Medicals for Rs.10, 000 + endorsements and license issue fees around Rs. 25k + Type Rating around Rs. 15 Lacs. So, decide wisely before you enter the field.

I recently visited the campus of Indo Global Colleges near Chandigarh which is one of the finest & excellent college of BCA in terms of ranking, reputation, the oldest, affiliation, best learning environment, state of the art infrastructure with well-equipped labs, workshops, digital classrooms equipment and tools etc. , beautiful surroundings, strong industry exposure & tie-ups, well qualified and experienced faculty & top placements. This college has tie-up with all leading academic and industrial top companies i.e. IIT Bombay, IIT Delhi and Chennai, IBM, Cisco, Red Hat, Oracle, etc. I met concerned HOD of the computer science and he guided me very well. I'm sharing my experience based on my recent experience about this college on computer science and BCA.
