Dear Nimi, for bachelor degree you must have excellent grades particularly in mathematics. Aerospace is a sub field of mechanical engineering so you will mostly find a bachelor's degree in mechanical engineering.You can select the required specialization during the final year. As an applicant you must take SAT and TOEFL or IELTS. For more requirements you are required to visit university websites.

Hi, check the top universities of Singapore NUS and NTU. They are selective universities and usually higher grades are preferred. Scholarships again are on merit basis and depends on an individual application package. Please visit the websites and prepare for your application according to their requirements.

Hi
JCU, PSB then Amity is the order of preference as per the parameters of world ranking, placements and degree. JCU has the best ranking in world as well as singapore than the rest two and it doesn't require work experience or GRE/GMAT too.
Hope this suffice.

Your question about certificate programs can not be compared with MBA Abroad in cost as well as duration. if you ready to spend 10 lakhs tuition fees you can do your MBA abroad

Dear Rahul, you may start by visiting websites like QS world ranking or financial times Ranking. You will find the best universities in every country. Visit the university websites for details such as programs they offer, fees, requirements etc. Unless you take a look at the websites yourself it won't help much.
