The overall coordination and responsibility lies with Indian Institute of Science, Bangalore designated as the Organizing Institute for GATE 2008.

Admission to post graduate 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 degree in Engineering/ Technology/ Architecture/ Pharmacy or Master 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 additionally 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 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 in Engineering disciplines are also eligible for the award of Junior Research Fellowship in CSIR Laboratories. Some government organizations prescribe GATE qualification as a requirement for applying to the post of a Scientist/Engineer.

GATE Main Papers Pattern

The question paper will be for a total of 150 marks divided into three groups:

(i) Group I: Question Numbers 1 to 20 (20 questions) will carry one mark each (sub total 20 marks).

(ii) Group II: Question Numbers 21 to 75 (55 questions) will carry two marks each (sub total 110 marks). Out of these, Q.71 to Q.75 may be common data based questions.

(iii) Group III: Question Numbers 76 to 85 (10 questions) will carry two marks each (sub total 20 marks). These questions are called linked answer questions. These 10 questions comprise five pairs of questions (76 & 77, 78 & 79, etc.). The solution to the second question of each pair (e.g. Q.77) will be linked to the correct answer to the first one (e.g. Q.76) in the pair.

Each question will have four choices for the answer. Only one choice is correct. Wrong answers carry 25% negative marks. In Q.1 to Q.20, 0.25 mark will be deducted for each wrong answer and in Q.21 to Q.76, Q.78, Q.80, Q.82 and Q.84, 0.5 mark will be deducted for each wrong answer. If the first question in the linked pair is wrong, then the second question in the pair will not be evaluated. However, there is no negative marking for the linked answer questions - Q.77, Q.79, Q.81, Q.83 and Q.85. Papers bearing the code AE, AG, CE, CH, CS, EC, EE, IN, IT, ME, MN, MT, PI, TF will contain questions on Engineering Mathematics to the extent of 20 to 25 marks. The multiple choice objective test questions can be of the following type: (i) Each choice containing a single stand-alone statement/phrase/data. Example Q. The state of an ideal gas is changed from (T1, P1) to (T2, P2) in a constant volume process. To calculate the change in enthalpy, Dh, ALL of the following properties/variables are required. (A) Cv, P1, P2 (B) Cp, T1, T2 (C) Cp, T1, T2, P1, P2 (D) Cv, P1, P2, T1, T2 (ii) Each choice containing a combination of option codes. The question may be accompanied by four options P, Q, R, S and the choices may be a combination of these options. The candidate has to choose the right combination as the correct answer. Example Q. The following list of options P, Q, R and S are some of the important considerations in the design of a shell and tube heat exchanger. P: square pitch permits the use of more tubes in a given shell diameter Q: the tube side clearance should not be less than one fourth of the tube diameter R: baffle spacing is not greater than the diameter of the shell or less than one fifth of the shell diameter. S: the pressure drop on the tube side is less than 10 psi (A) P, Q and R (B) Q, R and S (C) R, S and P (D) P, Q, R and S (iii) Assertion[a]/Reason[r] type with the choices stating if [a]/[r] are True/False and/or stating if [r] is correct/incorrect reasoning of [a] Example Q. Assertion [a]: Bernoulli's equation can be applied along the central streamline in a steady laminar fully-developed flow through a straight circular pipe. Reason [r]: The shear stress is zero at the centre-line for the above flow. (A) Both [a] and [r] are true and [r] is the correct reason for [a] (B) Both [a] and [r] are true but [r] is not the correct reason for [a] (C) Both [a] and [r] are false (D) [a] is false but [r] is true (iv) Match items: Match all items in Group 1 with correct options from those given in Group 2 and choose the correct set of combinations from the choices E, F, G and H. Example Q. Group 1 contains some CPU scheduling algorithms and Group 2 contains some applications. Match entries in Group 1 to entries in Group 2. Group 1 Group 2 P- Gang Scheduling 1- Guaranteed Scheduling Q- Rate Monotonic Scheduling 2- Real-time Scheduling R- Fair Share Scheduling 3- Thread Scheduling (A) P-3; Q-2; R-1 (B) P-1; Q-2; R-3 (C) P-2; Q-3; R-1 (D) P-1; Q-3; R-2 (v) Common data based questions: Multiple questions may be linked to a common problem data, passage and the like. Two or three questions can be formed from the given common problem data. 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 Questions 74 and 75: 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.74 The mean of the random variable Y is (A) 1/2 (B) 1 (C) 3/2 (D) 2 Second question using common data Q.75 The variance of the random variable Y is (A) 1/2 (B) 2/3 (C) 1 (D) 2 (vi) 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 80 and 81: 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.80 How many data cache misses will occur in total? (A) 48 (B) 50 (C) 56 (D) 59 Second question of the pair Q.81 Which of the following lines of the data cache will be replaced by new blocks in accessing the array for the second time? (A) line 4 to line 11 (B) line 4 to line 12 (C) line 0 to line 7 (D) line 0 to line 8

GATE XE Section A Paper Pattern

XE section A paper will be for 30 marks. It will consist of fully objective type and the questions are divided into two groups. (i) Group I: Question Numbers 1 to 6 (6 questions) will carry one mark each (subtotal 6 marks). (ii) Group II: Question Numbers 7 to 18 (12 questions) will carry two marks each All questions have four choices with only one being correct. Wrong answers carry 25% negative marks. In Q.1 to Q.6, 0.25 mark will be deducted for each wrong answer and in Q.7 to Q.18, 0.5 mark will be deducted for each wrong answer. The pattern of multiple-choice questions is the same as described for the main papers.

GATE XE Section Paper Except for Section-A

All sections apart from section A are for 60 marks each. Each of the 60 mark section will be fully objective type and the questions are divided into three groups. (i) Group I: Question Numbers 1 to 8 (8 questions) will carry one mark each (subtotal 8 marks). (ii) Group II: Question Numbers 9 to 30 (22 questions) will carry two marks each (subtotal 44 marks). Out of this, Q.29 and Q.30 may be common data based questions. (iii) Group III: Question Numbers 31 to 34 (4 questions) will carry two marks each. These questions are called linked answer questions. These 4 questions comprise two pairs of questions (31, 32 and 33, 34). The solution to the second question of each pair (e.g. Q.34) will be linked to the correct answer to the first one (e.g. Q.33) in the pair (subtotal 8 marks). All questions have four choices with only one being correct. Wrong answers carry 25% negative marks. In Q.1 to Q.8 of each section, 0.25 mark will be deducted for each wrong answer and in Q.9 to Q.31 and Q.33, 0.5 mark will be deducted for each wrong answer. If the first question in the linked pair is wrong, then the second question in the pair will not be evaluated. However, there is no negative marking for linked answer questions Q.32 and Q.34. The pattern of multiple-choice questions is the same as described for the main papers.

GATE Result and Score Card

GATE results
GATE 2008 results will be announced on March 15, 2008 at 1000 hours at GATE offices of IISc/IITs. It will also be available on the websites of IISc/IITs. With effect from GATE 2008, the GATE website will provide the GATE scores to both qualified and non-qualified candidates. GATE 2008 score is valid for two years from the date of announcement of the GATE 2008 results.

GATE scorecard
Scorecard will be sent only to the qualified candidates. No information will be sent to candidates who are not qualified. The GATE scorecard is a valuable document. Care should be taken to preserve it. Additional scorecards (upto a maximum of two) will be issued on payment basis only once. The scorecard cannot be treated as a proof of date of birth, category and disability status. The scorecard will indicate GATE score and rank of the qualified candidates.

GATE score
The GATE score of a candidate is in the range 0 to 1000. It reflects the performance of a candidate, irrespective of the GATE paper or year in which he/she has qualified. Candidates with same GATE score from different GATE papers and/or years can be considered to have the same performance level. The marks obtained by the candidate is normalized on the basis of the average and standard deviation of marks of all candidates who appeared in the paper mentioned on the scorecard in GATE 2008. Subsequently, this is scaled with respect to the global average and global standard deviation so as to facilitate performance comparison across GATE papers and over a block of years since GATE 2005.

GATE SCORE = (1000/500)[a1 + s1((m-a)/s)]

Where
m = marks obtained by the candidate.
a = average of marks of all candidates who appeared in the paper mentioned on this scorecard in GATE 2008
s = standard deviation of marks of all candidates who appeared in the paper mentioned on this scorecard in GATE 2008
a1= global average of marks of all candidates who appeared across all papers and years (2005-2008)
s1= global standard deviation of marks of all candidates who appeared across all papers and years (2005-2008)
The maximum score can be 1000.
The evaluation of the ORS is carried out by a computerized process using scanning machines, with utmost care. Requests for revaluation of the answer script and re-totaling of marks will not be entertained.
The GATE results of the qualified candidates will be made available to interested organizations (educational institutions, R & D laboratories, industries, etc.) in India and abroad based on written request by the organization and on payment. Details can be obtained from GATE Chairmen of IITs/IISc.

Preparing for GATE

Preparing for GATE can be as easy as preparing for your college examinations. Just take little cautions while studying any topic and do remember that GATE paper focus on your in depth knowledge of subject, your basics, presence of mind during examination etc.

We’ll recommend following while preparing for your GATE exams people may differ as this is my personnel opinion :

1. Always follow standard books for GATE. Try to cover complete syllabus. If not possible expertise in what ever portion of syllabus you practice.
2. Try preparing notes after reading every chapter/topic. This may initially take some time but will help you while revising before paper. Click here for expert tips to prepare notes for GATE.
3. While reading any chapter/topic do ask your self following questions “What”, “How”, and “Why” and see improvement
4. Best way to prepare is to follow cycle Learn, Test, Analyze, Improve, Learn, Test, Analyze, Improve ……
   Youdowetest.com can help you when you test your self for GATE and its free.
5. Do remember that GATE is completely objective question based test. Most of time solving objective questions is tricky. Learn tips to solve GATE objective questions from GATE Tutor .
6. In case of doubts do ask some expert or use forums to discuss questions as provided by youdowetest.com
7. Don’t worry if your percentage in university exams is low as GATE admissions do not consider them. Just maintain minimum percentage required by many colleges including IIT’s. Look at GATE Cutoff and eligibility section to know eligibility and cut off of various colleges.
8. Group study is one of the best ways of preparation. Divide sections/topics between you and your partner and have a brief session on topic from your friend before you actually start topic. This will save your time and efforts and will improve your and your partner’s understanding on the topic.
9. Normally coaching GATE is not required but if you are not able to concentrate much then this is a good option.
