Here, I have mentioned some IITs accepting JAM scores and their eligibility criteria. Form. Sc. Candidate must have Bachelors degree (Geology) and any two subjects among Chemistry, Mathematics, and Biological Science Physics. Also, the candidate must have passed 12th with Math as a mandatory subject. Form. Sc. In IITB Candidate must have passed graduation with both Mathematics and Physics for two years and at least one out of these two for three years. Form. Sc. Biotechnology in IITB and IITR Candidates must have done graduation degree in any of these (Science, Agriculture, Pharmacy, Veterinary, Engineering, and Medicine) branches. Form. Sc. Chemistry in IITG, IITK, IITB, IITD, IITM, and IITR Candidate must have done a graduate degree in chemistry and also candidate must have passed 12thwith mathematics. Form. Sc. Mathematics in IITB, IITD, IITK, and IITM Candidate must have done graduation with Math as a subject for minimum two years or four semesters. Form. Sc. Physics in IITB, IITD, IITG, IITK, IITM and IITR) or Joint. Sc. /Ph.D. (Physics) in IITK Candidate must have done graduation with Physics for minimum two years/ four semesters and also must have done graduation with math for at least one year or two semesters. Form. Sc. Or Ph.D. in Geophysics at IITK Candidate must have done graduation with any two subjects from Physics, Mathematics and Geology minimum 3 years and 6 semesters. Form. Score Ph.D. (Dual Degree) in IITB Candidate must be a graduate in any one of these subjects Physics, Chemistry and Math for minimum two years and four semester.

Student Pilot License (SPL) & Private Pilot License (PPL) are intermediate stages of Commercial Pilot License Training.
You will be issued an SPL by the flying club after some hours of ground classes and an internal exam. Thereafter you shall become eligible to start flying training.
Its very simple logic SPL - PPL - CPL.
YOU CAN SKIP PPL AS IN ANY CASE YOU ARE ASPIRING FOR A HIGHER LICENSE, WHICH WILL ALLOW YOU MORE PRIVILEGES THAN PPL.
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 visithttp://www.dgca.nic.in/medical/medical-ind.htmandgototheclass 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.
