CBSE 12th

Eligibility:10+2 with 50% in Physics and Math. Minimum age Requirement: 18Medical Class I and Class II (Medical fitness should be in accordance to DGCA guidelines)
Steps to apply:
1. Now the very first step is to get Medical examination 2 done. Only after Medical exam 2 reports, one can apply for medical certificate 1. Just visit Directorate General of Civil Aviation, Government of India's website and they have a long list of doctors who are certified to issue that certificate.
2. Next step is to apply to the respective flying school and clear their entrance exams to get through one of these:
APFT. , Hyderabad
Academy of Carver Aviation, Baramati
Ahmedabad Aviation & Aeronautics Ltd. , Ahmedabad
Chimes Aviation, Sagar, (Madhya Pradesh) Madhya Pradesh- call in October
Government. Aviation Training Instt. , Orissa
Indira Gandhi Rashtriya Udan Academy, Raebareilly
Madhya Pradesh Flying Club, Indore
National Flying Training Institute, Gondia
Besides these few colleges which are the top ones, one can also look at the of other flying schools as listed by DGCAhttp://dgca.gov.in/licencing/fly. In the above mentioned Institutes students can complete CPL. However attaining CPL allows one to fly CESSNA (small planes). In order to fly Bigger Airplanes one needs to attain TYPE RATING certificate. The full-fledged course (CPL plus Type rating) can be done from Cadet Pilot programme (Indigo and JET Airways Cadet Programs at National Flying Training Institute, Gondia). Here is the list of Licenses that one will be trained on in the flying school/you can attain them without going to a flying school:
Student Pilot License (SPL): SPL is like learners license. One must have SPL prior to start flying training. Oral test is conducted by Chief Instructor at flying school or by DGCA representative.

In this competitive scenario, students start preparing for entrance exams at a very early stage while still in their school days. While entrance exams are their gateway after their 10+2, to get seats in good engineering colleges, it is a fact that the effort and dedication required for this is massive. The struggle to get admission on the basis of entrance exam is huge because the competition and performance pressure exceeds countable limits. Amidst this pressure and performance play, some candidates fail to cope up and end up disappointed. Some of them choose not to appear for all the entrance exams and choose one or two. Increasingly, many students are looking for the engineering admissions on the basis of their class 12th marks. It is one means of availing admissions in some good colleges and universities. However, the details about B.Tech admissions on the basis of Class 12th are not really well known. Shiksha has compiled the information regarding admission to B.Tech on the basis of class XII in this article for students who do not wish to take part in rat race that constitutes engineering entrance exams in India. This information will be useful to even those students who have not been able to score well in JEE Main. https://www.shiksha.com/b-tech/colleges/b-tech-colleges-india
