Degree

Hi Vishakha,
English speaking students should not have problems as most universities offer courses in English but at the undergraduate level, it can be difficult to find these. In any case, it is better to check university websites for the language of instruction. You will also not find B.Arch course, in particular, most programs will be termed as Urban Planning, etc. You can check Leiden University, University of Groningen, Royal University of Art and The Hague offers a Bachelor's degree in interior architecture.

Airline Transport Pilot License (ATPL) is the final and top most License that any pilot can attain. Unlike Commercial Pilot License (CPL), ATPL also has certain specified eligibility criteria.
It is only issued to those pilots who hold a valid and current CPL + have cleared DGCA ATPL exams + have attained 1500hours of flying experience.
Hence to get an ATPL the pilot has to justify all the above mentioned requirements.
So first aim for CPL then get a job and then clear exams + flying to get an ATPL.
No flying school trains directly to get an ATPL.
