About GATE
GATE exam is likely to be held on February 1, 2, 8 and 9. IIT Roorkee will soon release theGATE exam date. The GATE Exam is a nationwide exam that is taken by around 9 lakh students each year. The GATE Score has a lot of importance because all major universities that accept students use the GATE Score in their admission process, and the same is true for PSUs (Public Sector Undertakings).
The examination assesses the graduate engineer's understanding of the fundamental concepts in the field, such as discrete mathematics, digital logic, programming and data structures, compiler design, and others.
