Paper specific instructions: 
 
1. There are a total of 65 questions carrying 100 marks. Questions are of multiple choice type or 
numerical answer type. A multiple choice type question will have four choices for the answer with 
only one correct choice. For numerical answer type questions, the answer is a number and no choices 
will be given. A number as the answer should be entered using the virtual keyboard on the monitor. 
 
2. Part-A is a compulsory section that contains 25 questions carrying  1 mark each. Part-B contains two 
optional sections: Section 1 (Geology) and Section 2 (Geophysics). Each of these sections contains 30 
questions carrying 2 marks each. The 2 marks questions include two pairs of common data questions 
and two pairs of linked answer questions. The answer to the second question of the linked answer 
questions depends on the answer to the first question of the pair. If the first question in the linked pair 
is wrongly answered or is not attempted, then the answer to the second question in the pair will not be 
evaluated. 
 
3. Questions Q.56 – Q.65 belong to General Aptitude (GA) section and carry a total of 15 marks. 
Questions Q.56 – Q.60 carry 1mark each, and questions Q.61 – Q.65 carry 2marks each.  
 
4. Questions not attempted will result in zero mark. Wrong answers for multiple choice type questions 
will result in NEGATIVE marks.  For all 1 mark questions, ? mark will be deducted for each wrong 
answer. For all 2 marks questions, ? mark will be deducted for each wrong answer.  However, in the 
case of the linked answer question pair, there will be negative marks only for wrong answer to the 
first question and no negative marks for wrong answer to the second question. There is no negative 
marking for questions of numerical answer type. 
 
5. Calculator is allowed. Charts, graph sheets or tables are NOT allowed in the examination hall.  
 
6. Do the rough work in the Scribble Pad provided.
