Hey, here are some important information about AME -:
The AME course is for the students who have cleared their normal engineering and want to do their specialization in aviation field. Although the eligibility for the course is 12th Std. But when you go for a job interview, the one with a regular degree gets higher percentage of chance of getting the job.
Also it is not necessary for you to get into some college or institute to get AME license. In fact if you are really interested to get into the aviation field, then

1. Get a regular college engineering degree(any engineering degree approved by UGC)
2. Enroll yourself for a training program in Air India or any other institute related to the aviation through your influences, some fees etc. min 6 months to get yourself acquainted with the work you are going to get to do.
3. Search for a job.( Believe me, you can get a job in the Indian Aviation industry with a regular degree and a basic 6 month training within a reputed company more easily than with a AME course certification.)
4. Apply for Paper I to DGCA, Central Govt. of India after you have acquired the needed experience through training.(forms are easily available, if you Google it)
5. Once you start studying for your first paper, you will get to know everything that is required to survive in the aviation industry.

Good Luck :)
