Actually they don't expect you to be topper in GATE..they want only 90 percentile which means even if you clear GATE with just 1 or 2 marks more than cut off you also can get the call. They don't care about your score or rank . It's just to be shortlisted in 1st round then they will judge you by your overall profile. So, it really means nothing if you get 99.99 or 91 percentile. Next step is important . As far I've heard good profile means

1. GOOD GPA(>8.00)
2. CLASS 10 & 12 MARKS
3. PUBLICATIONS
4. WORK EXP
5. SOP
6. LORs
7. ACTIVITIES
8. TOEFL SCORE(>90 )
9. INTERNSHIPS
10. CONTRIBUTION TOWARDS RESEARCH
11. PRIOR RESEARCH EXP
12. PROJECTS

Actually with GATE score anyone just only can apply for M.Engg both in NUS NTU so they really care a lot about your prior research exp.
