You need to understand that pilot training is governed and regulated by DGCA and it is irrespective of the flying school you choose to train with. For becoming a commercial pilot, there is a specific eligibility criterion, 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 visit http://www.dgca.nic.in/medical/medical-ind.htm and go to the class 2nd examiner's tab to find out doctors who will examine you for initial fitness. You can visit any doctor 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 this field.

Firstly ascertain your priorities, Do you want to do BCA for Knowledge or just for Money or just to save Money for your future degree. Let me answer considering Knowledge as an aspect: B.Tech being a 4 year course has better chances of imparting you indepth knowledge of Computer Science (am assuming you will go for CS/IT if you do B.Tech). But then a lot depends on the college you join. As I already said better chances but no guarantee. 3 cousins of mine used my Final year project to pass their B.Tech (I think I forgot to tell I am a BCA). So the assumption that B.Tech will give you better understanding of subject is a notorious one. Moving on to Money you would make or Money you would spend: I spent almost 1.1 Lacs (including the cost of computer I bought, I assume you already have one) in completing my BCA from a non funded seat of government college, which is a big saving compared to expenses you will meet while doing B.Tech from private engineering college. Now how much would you make, So let me tell you my story, I joined Infosys after completing my BCA at a package of 2.25 Lacs in January 2011 (hired as on Operations Executive), was elevated to 3.50 Lacs (promoted to System engineer) in month of October 2013 and I am currently earning 4.20 Lacs (Senior System engineer). B.Tech fresher were being hired at some where between 3.20 - 3.50 in 2011 (I don't know current package being offered to them) and in the same time if they haven't left the organisation yet are earning somewhere around 4.50 - 5 Lacs. So basically it took me almost 2 Years to match the package at what B.Tech were hired, and this difference will always remain until and unless of course I leave the organisation and join somewhere else at better package, but that applies to B.Tech as well which is entirely a different story. I would also like to tell you not only are we paid lesser in Infosys but are also treated as lesser employees. In projects where client do not have specific requirements for 12+4 year educated employees, BCA are put in such projects to do menial jobs which B.Tech smart asses won't do, like updating excels or doing monitoring or regulating mails or more menial things like taking calls. Almost all BCA pupil end up spending at least 2 and at max inly God knows how many years for studying only 1 year less than B.Tech.
