Geology and Geophysics Paper
Apart from the General Aptitude section, the Geology and Geophysics question paper includes two different parts: Part A & Part B. Part A is same for all candidates. Part B includes two different sections: Section 1 (Geology) & Section 2 (Geo-physics). Part 1 is compulsory for all the Candidates. From part B, candidates can opt for either Section 1 or Section 2.
