GATE which stands for Graduate Aptitude Test for Engineering  is one of the toughest test, an all India Examination that generally test the comprehensive understanding of various undergraduate subjects in Engineering and Technology.

Exam duration is 3 hours with syllabus and pattern varying from paper to paper. This Exam is being conducted via two modes- Online and Offline, either can be opted.

GATE Syllabi

Exam Structure-
One candidate can only appear for One paper out of all 21 papers.The choice of paper is up to the candidate .3 hours duration exam consisting of 65 questions with maximum marks 100.The Question paper contains only objective type questions. Every GATE paper will have questions on General Aptitude carrying 15 marks which is common in all papers. There is also negative marking for wrong answers.

Geology is the science that comprises of detail study of solid Earth that is the rocks of which it is composed of and the process by which they change.Geophysics is the physics of earth that is study of Earth using quantitative physical methods.Geophysicists career scope are quite good as it involves a vast range of fields where one can specialize.Good job prospects in India as well as in Abroad.This field is not only challenging but also provides excellent remuneration.Geologists have good career prospects and as they hold a very important role in the exploration of valuable mineral resources, they can get good jobs in private sectors as well as firms of government.They can also pursue research in institutes like Cairn India Limited, Essar Oil limited, Coal India Limited etc.
