GATE Engineering Sciences Statistics
Below are some interesting statistics about this paper. We will see derive important facts based on this statistics.
- Number of candidates registered for the exam – 3700 (approx)
- Number of candidates appeared for the exam – 3100 (approx)
- Number of qualified candidates – 566
- Percentage of candidates qualified – 21% (approx)
- Maximum marks out of 100 – 78.33
- Minimum marks out of 100 – 18
- Average marks – 33.54
- Standard Deviation – 8.95
The percentage os pass candidates is higher in this paper compared to other papers. This makes a easy paper to clear GATE exams.The highest marks is 78 but lowest is 18. So there is huge gap between highest and lowest marks. The average marks is also close to lowest marks.
This means majority of candidates score in range of 25 to 45. So if you can score above 55 then you will get good rank.Now based on these finding you can plan your preparation.Below I will share preparation material.
