Hello Friends,
Gate exams is conceptual oriented,
Mathematics is key for it,
If someone not feel good for gate coaching, try to solve test series online.
You can do 75% of syllabus from any stream(Maths and aptitude don't exclude)
Visualization is very important to clear concept.
Many PSU's accept gate score card,Salary range from 5lakhs-11 lakhs(6th pay commission)
In 7th pay commission it may rise to 20-30%
