Question pattern
Multiple Choice Questions
Multiple choice questions in all papers and sections will contain four answers, of which only one is correct. The types of questions in a paper may be based on following logic:
(i) Recall:
These are based on facts, principles, formulae or laws of the discipline. The candidate is expected to be able to obtain the answer either from his/her memory of the subject or at most from a one-line computation.
Example
Q. During machining maximum heat is produced
(A) in flank face (B) in rake face
(C) in shear zone (D) due to friction between chip and tool.
(ii) Comprehension:
These questions will test the candidate's understanding of the basics of his/her field, by requiring him/her to draw simple conclusions from fundamental ideas.
Example
Q. A DC motor requires a starter in order
(A) to develop a starting torque
(B) to compensate for auxiliary field ampere turns
(C) to limit armature current at starting
(D) to provide regenerative braking
(iii) Application:
In these questions, the candidate is expected to apply his/her knowledge either through computation or by logical reasoning.
Example:
Q. The sequent depth ratio of a hydraulic jump in a rectangular channel is 16.48. The Froude number at the beginning of the jump is:
(A) 10.0 (B) 5.0
(C) 12.0 (D) 8.0
(iv) Analysis and Synthesis:
These can be linked questions, where the answer to the first question of the pair is required in order to answer its successor. Or these can be common data questions, in which two questions share the same data but can be solved independently of one another.
Common data questions:
Multiple questions may be linked to a common data problem, passage and the like. Two or three questions can be formed from the given common data problem. Each question is independent and its solution obtainable from the above problem data/passage directly. (Answer of the previous question is not required to solve the next question). Each question under this group will carry two marks.
Example
Common Data, for instance, Questions 48 and 49 in main paper:
Let X and Y be jointly distributed random variables such that the conditional distribution of Y, given X=x, is uniform on the interval (x-1,x+1). Suppose E(X)=1 and Var(X)= 5/3
First question using common data:
Q.48 The mean of the random variable Y is
(A) 1/2 (B) 1 (C) 3/2 (D) 2
Second question using common data:
Q.49 The variance of the random variable Y is
(A) 1/2 (B) 2/3 (C) 1 (D) 2
Linked answer questions:
These questions are of problem solving type. A problem statement is followed by two questions based on the problem statement. The two questions are designed such that the solution to the second question depends upon the answer to the first one. In other words, the first answer is an intermediate step in working out the second answer. Each question in such linked answer questions will carry two marks.
Example:
Statement for Linked Answer Questions, for instance, for Questions 52 and 53 in Main Paper:
The open loop transfer function of a unity feedback control system is given by
First question of the pair:
Q.52 The value of K which will cause sustained oscillations in the closed loop system is
Second question of the pair:
Q.53 The frequency of sustained oscillations is
The questions based on the above four logics may be a mix of single stand alone statement / phrase / data type questions, combination of option codes type questions or match items types questions.

GATE EXAMINATION STRUCTURE
EE Electrical Engineering
GATE Examination Type
The GATE examination consists of a single paper of 3 hours duration which contains 65 questions carrying a maximum of 100 marks. The question paper will consist of only objective questions.
The candidates will have to mark the correct choice on an Optical Response Sheet (ORS) by darkening the appropriate bubble against each question. There will be negative marking for each wrong answer, except for the numerical answer type questions.
Each GATE paper shall have a General Aptitude (GA) component carrying 15 marks.
GATE 2012 would contain questions of four different types in various papers:
• Multiple choice questions carrying 1 or 2 marks each.
• Common data questions, where two successive questions use the same set of input data.
• Linked answer questions, where the answer to the first question of the pair is required in order to answer its successor.
• Numerical answer questions, where the answer is a number, to be entered by the candidate.
In all the papers, there will be a total of 65 questions carrying 100 marks, out of which 10 questions carrying 15 marks in General Aptitude (GA) are compulsory.
Engineering Mathematics will carry 15 % of the total marks, the General Aptitude section will carry 15 % of the total marks and the remaining 70 % of the total marks is devoted to the subject of the paper.
For 1 mark multiple choice questions, 1/3 mark will be deducted for a wrong answer. Likewise, for 2 marks multiple choice questions, 2/3 mark will be deducted for a wrong answer. However, for the linked answer question pair, where each question carries 2 marks, 2/3 mark will be deducted for a wrong answer to the first question only. There is no negative marking for wrong answer to the second question of the linked answer question pair. If the first question in the linked pair is wrongly answered or is unattempted, then the answer to the second question in the pair will not be evaluated. There is no negative marking for numerical answer type questions.
Pattern of Question Papers
General Aptitude (GA) Section:
In all papers, GA questions are of multiple choice type, and carry a total of 15 marks. The GA section includes 5 questions carrying 1 mark each (sub-total 5 marks) and 5 questions carrying 2-marks each (sub-total 10 marks)
Question papers other than GG, XE and XL:
These papers would contain 25 multiple choice questions carrying one mark each (sub-total 25 marks) and 30 multiple choice questions carrying two marks each (sub-total 60 marks). Out of these, two pairs of questions would be common data questions, and two pairs of questions would be linked-answer questions.
