GATE Metallurgical Engineering Statistics
Below are some interesting statistics about this paper
- Number of candidates registered for the exam – 4,500(approx)
- Number of candidates appeared for the exam – 3,600(approx)
- Number of qualified candidates – 961
- Percentage of candidates qualified – 26% (approx)
- Maximum marks out of 100 – 73
- Minimum marks out of 100 – 28
- Average marks – 45.55
- Standard Deviation – 8.93
This paper has one of the highest pass percentage compared to other papers of GATE exams.Normally GATE pass percentage is around 20% of candidates appeared for exams. But this paper it is approx 25% which is way higher than other papers or average pass percentage.
This makes it one of the easiest paper to crack GATE exams.Also the average marks is one of the highest compared to other papers.You should score more than 60 to score good rank in this paper.The majority of candidates have amrks in range of 35 to 55.You can refer below study materials to crack the exams with ease.
GATE Metallurgical Engineering online tests
GATE Metallurgical Engineering paper does not have good amount of resources online.So candidates preparing for GATE Metallurgical Engineering paper find difficult to prepare.So we created this online test series to help them in preparation.
The test was created with current GATE exams in mind.Only questions important for upcoming GATE exams are included.You can try the online tests using below links.
For best results try all the tests.All tests have unique sets of questions.The tests also have negative marking and time limit.So you can try them after preparing.This help you see how well prepared you are for GATE exams.
GATE Metallurgical Engineering recommended books
I will recommend below books for this paper. The first book is theory and questions book. The second book is for questions only. You should prefer first book but due to any reason if you do not want to buy first book then buy second book.
With first book you get 24*7 access to online portal as well as mobile app for better preparation. The second book has chapter-wise solved paper for last seventeen years. The second book also has some tips and tricks in each chapter. These things are useful in exams.
In fact you should buy both the books.One will be good for theory and other one will be good for problem solving.
