Am interested in studying Aerospace Engineering at USA top tier universities. Currently completing my A levels from Bangladesh what type of ECAs should I do?
A lot of Aerospace has foundations in mechanical engineering, so anything related is beneifical - work experience, personal/team projects etc.
If you're aiming for a 'top tier' uni then an academic profile will be extremely valuable, and not just A-Levels.
If there are any maths or physics challenges/olympiads you could take part in then that would help support your application.
Extra reading around the course is also another really exploitative option.
