Geology and Geophysics GATE 2020 Syllabus
Candidate should refer to the GATE 2020 (GG) Syllabus officially prescribed by the GATE 2020 conducting institute, Indian Institutes of Technology Delhi. The syllabus of GATE exam is based on graduation level. The exam paper carries 85% marks from the technical subjects and 15% of marks from the General Aptitude section. Applicants are advised to check the complete syllabus before starting the preparation of exam.
The syllabus of GATE GG subject is very vast and categories into 3 sections – Geology, Geophysics and Common to both. As all the sections don’t have equal marks distribution, so more efforts are required to make a priority list of subjects based on marks distribution in the previous exams. This exercise will help you prioritize and allocate preparation time to different topics.
