Graduate Aptitude Test in Engineering (GATE) is an all-India examination administered and conducted jointly by the Indian Institute of Science and seven Indian Institutes of Technology on behalf of the National Coordinating Board - GATE, Department of Education, Ministry of Human Resource Development (MHRD), Government of India.

The overall coordination and responsibility of conducting GATE 2009 lies with Indian Institute of Technology Roorkee, designated as the Organizing Institute for GATE 2009.

Admission to postgraduate programmes with MHRD and some other government scholarship/assistantship at engineering colleges/institutes in the country are open to those who qualify through GATE.


GATE qualified candidates with Bachelor's degree in Engineering/ Technology/ Architecture/ Pharmacy or Master's degree in any branch of Science/Mathematics/Statistics/Computer  Applications are eligible for Master / Doctoral programmes in Engineering /Technology/ Architecture/Pharmacy as well as for Doctoral programmes in relevant branches of Science. To avail the scholarship, the candidate must secure admission to such a postgraduate programme, as per the prevailing procedure of the admitting institution. GATE qualification, however, is not required for candidates with Master's degree in Engineering /Technology/Architecture/Pharmacy, who may be seeking scholarship/ assistantship for relevant doctoral programmes. Some institutions specify GATE as the mandatory qualification even for admission of self-financing students to postgraduate programmes. GATE qualified candidates are also eligible for the award of Junior Research Fellowship in CSIR Laboratories and CSIR sponsored projects. Some government organizations prescribe GATE qualification as a requirement for applying to the post of a Scientist / Engineer.

Many students may not be aware that there are several institutions in this country, offering specialized postgraduate programmes in various disciplines. Attractive scholarship/Assistant-ship for postgraduate courses in engineering/Technology/Archi-tecture/Pharmacyat Engineering colleges/institutes in the country are available to those who qualify through GATE. Some Engineering colleges/institutes specify GATE as a mandatory qualification even for admission to post graduate programmes. The candidate is required to find the procedure of final selection and award of scholarship/ Assistant-ship from the respective Institution to which the candidate seeks admission. GATE qualified candidates in Engineering subjects) will also be eligible for the award of junior research fellowship in CSIR Laboratories.

The objective of ATE is identify meritorious and motivated candidates for admission to Post Graduate Programmes in Engineering, Technology, Architecture and Pharmacy at the National level, to serve as benchmark for normali-sation of the Undergraduate Engineering Education in the country.

Why should we take GATE
1. M.Tech degree leads to specialization and furthering of interest in a certain area which may lead to Ph.D
M.Tech degree is best for those wishing to apply for Faculty/Research positions in educational Institutes/R&D centers.
Examination Details
1. The examination is a single paper of 3 hours duration and generally consists of Section A (Objective Type) which is of 75 marks and Section B (Problem Type) which is of 75 marks. Total: 150 marks.
2. You have to opt for your subject and study as per the syllabus mentioned in the GATE brochure.
3. The subjects of our interest are Computer Science and Engineering, Electronics & Communication Engineering., Electrical Engineering and Instrumentation Engineering. Other subjects are also available such as Mathematics, Physics, etc.
4. Results of qualified candidates in GATE will give All India Rank and indicate percentile score. For example, a percentile score of 99 means you are in the top 1% category of the candidates who appeared for GATE.
5.Candidates who get less than 70 percentile get no score card.
6. GATE scores are valid for 2 years. You may reappear in the GATE exam if you are not satisfied with the earlier score and the new score (if better than the old one) will be used for admission purposes.
After the Exam, what next
1. After publication of GATE results, students must apply to individual Institutes to get their application forms.
2. Institutes advertise M.Tech admissions in leading news-papers from 1st April till end July. However some Institutes do not advertise and therefore students have to get the forms themselves.
3. In the application forms, you have to mention your GATE score alongwith other details.
4. The concerned Institute may conduct written test and/or interview for the purpose of admission.
5. Thumb rules: If your Gate score in Computer Science is 96 percentile or more then you can try for IITs, if between 85 - 96 percentile, then apply for top RECs, JADAVPUR, SHIBPUR, ROORKEE, etc. If less than 85, you have to look for appropriate institutes.

During the pursuit of M.Tech, you are paid a scholarship of Rs. 5000.00 per month by the Government of India. This amount is enough for living expenses including purchase of books, etc. The scholarship is paid for the entire 18 months M.Tech period.

We encourage 3rd year students to also appear for GATE alongwith Final Year students since:
a. GATE score is valid for 2 years.
b.The syllabus as required by GATE is generally over by 5th semester.

Types of 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.

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.

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.


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.

Common Data, for instance, Questions 55 and 56 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)=

First question using common data:

Q.55 The mean of the random variable Y is

(A) 1/2       (B) 1       (C) 3/2       (D) 2

Second question using common data:

Q.56 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.


Statement for Linked Answer Questions, for instance, for Questions 59 and 60 in Main Paper:

Consider a machine with a byte addressable main memory of 216 bytes. Assume that a direct mapped data cache consisting of 32 lines of 64 bytes each is used in the system. A 50x50 two dimensional array of bytes is stored in the main memory starting from memory location 1100H. Assume that the data cache is initially empty. The complete array is accessed twice. Assume that the contents of the data cache do not change in between the two accesses.

First question of the pair:

Q.59 How many data cache misses will occur in total?

(A) 48       (B) 50
