GATE Geology and Geophysics (GG) Syllabus 2024

GATE Geology and Geophysics Syllabus 2024 consists of two parts - Part A is the Common Section and Part B is further divided into two sections, section 1- Geology, and section 2- Geophysics.

Geology is a science that deals with the physical structure and substance of the earth. It also covers its history and the processes that act on it. Geophysics deals with the physical processes and phenomena occurring in the earth and in its vicinity.

Students are advised to start their preparation with covering the syllabus to ace the GATE exam.

GATE Geology & Geophysics Section-wise Syllabus

For this paper, 85% of the questions will be asked from the Geology & Geophysics sections while 15% of questions will be asked from the General Aptitude section. Candidates are advised to go through the GATE syllabus thoroughly as the knowledge of it is integral to their exam preparation.
