Sweden

Hello Mrunal, Sweden is an excellent place for study. The engineering programs are one of the best, and the universities have excellent industrial collaboration. Halmstad University's Mechanical engineering department is quite famous for all the good reasons.

Hi Aditya,
KTH Royal Institute of Technology is by the far the best known. Other well-known universities for aeronautical engineering are University of Gothenburg, Linkoping University and Swedish Institute for Space Physics. I hope this helps.

Hi Madala,
Admission requirements vary with the level of study and also depends on the university. Bachelor degree applicants are required to have at least 5.5 in each section while master degree students must have a score of 6.5 overall with no band less than 6.
Please note that this is just a minimum score requirement. Universities however, have special foundation programs for applicants not meeting English language requirements. For this, please contact the individual universities.
Hope this helps.
Good Luck.
