Aeronautical Engineering

Now, the marks of 12th standard are no longer important in giving JEE. You just have to secure more than 75%.

Hello Vishskha,
It's very nice to know your interest in Aeronautical engineering. But is it really do or are you meaning aircraft maintenance? These are entirely different. Best college without doubt is IIT M and then IISc. But job prospects of aeronautical engineering passing out of not so famous colleges is bleak. Think again please.

Both are niche branches of Engineering. Automobile industry and its ancillary industry is far bigger in comparison to Aeronautical Engineering industry. Therefore, based on job opportunities Automobile Engineering has more scope and job opportunities.

Yes, you can opt for aeronautical engineering after diploma in mechanical. You can get the direct second year entry though LEET.

Start preparing for IIT, there are also some top rated private colleges too. But I will suggest you to take a step forward, clear your mathematics, prepare for IIT, this will make your basics stronger then you will succeed in your field wherever you will study.

Hello Sachin,
Normally speaking, one needs diploma in the particular branch to be eligible for admission in engineering in that particular branch. However, many states and Institutions including IIT's accept diploma as equivalent to 12th and hence you can take admission to any branch of your choice in first year, after following due process.

Dear Khanisk,
If you are interested in aerospace, please join IIT or NIT or go abroad for studies. Most of the best is doing aerospace engineering in abroad like USA, UK, etc. Aircraft industry in India is not developed so there is limited chance of getting job in India.

Hello Sachin,
Many state governments have accepted equivalence of diploma with 12th. Hence on the basis of diploma you can seek admission in first year of any branch after of course following due process. Question of eligibility will arise if you are seeking admission in second year via lateral admission process. Here you need to refer to the particular University for getting clarity since many Universities follow different paths.

Many colleges are quite strict about the age criteria, you need to check the eligibility with the desired colleges for admission in diploma.
