Hi, I am Shubham Banik. I am a student of IIT-KGP and was lucky to have secured AIR-1 in the GATE 2023 examination in Geology branch. One of the books which played a pivotal role in my preparation was the Numerical Problems in Geology book by Mrinal Shreshtha. This is a must have book for GATE aspirants as it not only has all the formulas of Geology, it also has the explanations of different concepts as well as some of the important previous year questions. This is the book with which any aspirant of Geology must start their preparation for the GATE examination.
