Mechanical Engineering in Singapore

For Post Graduate engineering programs, a student should have a good Bachelor's degree in the relevant field of further study and the score of GRE/GATE is considered for Admissions. GATE is preferred more than GRE.
Candidates who have graduated from Indian universities may submit GATE scores instead.
Candidates should have a minimum GRE score of 320 (verbal & quantitative) and 3.5 (analytical), or a GMAT score of 650 and above. The minimum TOEFL scores for Internet Based Test (IBT) is 90; or IELTS score of 6.0. GRE and TOEFL scores will be valid for 5 years and 2 years respectively.

Hi Hidam,
Admission requirements vary from university to university. Normally GATE scores are required for international students in addition to TOEFL or IELTS scores. For the minimum score requirements please check university websites.
Hope it helped.
