Ans: Yes, there will be negative marking in the examination. Negative marking depends on the type and marks of questions. For NAT questions there will be no negative marking but for 1 or 2 marks ½ and 2/3 marks will be deducted respectively for wrong answers. 

Ans: Most marks are allotted to the GATE Metallurgical Engineering Syllabus 2023. The section weightage is as mentioned below:

Ans: Yes. Candidates can follow the below-mentioned books to prepare for the exam. Other than these books you are also advised to go through your graduation level books or notes to understand the basic concepts. 

• GATE 2023 – Metallurgical Engineering – Guide - GKP
• Metallurgical Engineering Solved Papers GATE 2023 - Amritansh Frank
• GATE 2023 – Solved Papers – Metallurgical Engineering-GKP
• Mechanical Metallurgy by George E. Dieter
• Mineral Processing by SK Jain
• Manufacturing Processes by RK Rajput
• Physical Metallurgy by V Raghvan 

Ans: The major topics of GATE Metallurgical Engineering syllabus 2023 are:

• Engineering Mathematics:
• Thermodynamics and Rate Processes
• Extractive Metallurgy
• Physical Metallurgy
• Mechanical Metallurgy
• Manufacturing Processes

Ans. GATE Syllabus typically requires at least 6 months to complete, if the candidate studies for at least 3 hours a day. However, GATE Metallurgical Engineering Syllabus can be completed within 2 months if the candidate dedicates a lot of time and effort. 

Ans. Along with GATE Metallurgical Engineering, candidates can also opt for PH (Physics) or XE (Engineering Sciences) as their secondary paper. However, these papers are to be given along with the Metallurgical Engineering paper and cannot be given exclusively.
