Geologist Exam Syllabus
The standard of the paper in General English will be such as may be
expected of a science graduate. The papers on geological subjects will be
approximately of the M.Sc. degree standard of an Indian University and questions
will generally be set to test the candidate's grasp of the fundamentals in each
subject.
There will be no practical examination in any of the subjects.
(1) General English
Candidate will be required to write a short Essay in English.
Other questions will be designed to test their under-standing of English and
workmanlike use of words.
