GATE- CHANGES IN RECENT YEARS

Changes in recent years

• From 2009 onwards, the IT and CS papers have been merged and there will be no separate IT paper.
• From 2010, Pharmacology is no longer on the GATE list, with GPAT as the replacement ^[2].

In 2009 the GATE score was valid only for one year but later the GATE committee made it valid for 2 years in 2010.

• From GATE 2010 onwards, an additional section of General Aptitude has been introduced in GATE. A total of 10 questions carrying 15 marks makes up this last section of GATE.

HOW TO APPLY FOR GATE

Applying to various institutes

GATE scores are only for application to graduate programs in Engineering disciplines in India. Usually IISc application dates are within 4–5 days of announcement of results. Most institutes do not specify their cut-offs for previous years. So there is a general confusion in terms of selecting institutes and specializations. But in the recent years IIT Kharagpur and Guwahati have been specifying last year cut-off mark list.
Typically the Indian Institute of Science is the most selective, very closely followed by the IITs. In general IISc and the IITs only admit students scoring among the top 3 percentile on the GATE, to their post-graduate programs.

</references/> The following list shows the percentile of GATE candidates and the respective institutes they are likely to get admission: 1) above 98 percentile-- apply for IIT's 2) between 96 and 98 percentile-- apply for institues like BHU, NIt warangal ,NIT Trichy,etc. 3) between 90 and 96 percentile-- apply for lower ranked NIT's and other engineering institutes 4) lower than 90 percentile-- apply for lower ranked NIT's but better admission chances in local colleges.

GATE EXAM PATTERN

QUESTION PAPER PATTERN

The question paper will consist of only objective type questions. Candidates have to mark the correct choice by darkening the appropriate bubble against each question on an Objective Response Sheet (ORS). There will be negative marking for wrong answers. The deduction for each wrong answer will be 25% of the allotted marks.

Each paper contains 60 questions carrying 100 marks.

Question Papers bearing the codes : AE, AG, AR, CE, CH, CS, CY, EC, EE, IN, MA, ME, MN, MT, PH, PI, PY and TF

Paper Code	Patterns of Question papers	Negative Marks for wrong Answer
AE, AG, AR, CE, CH, CS CY, EC, EE, IN, MA, ME, MN, MT, PH, PI , PY, TF	Q.1 to Q.20 : Will carry one mark each (sub-total 20 marks).	1/3 mark will be deducted for each wrong answer

Each question will carry two marks	There will be negative marks only for wrong answer to the first question of the linked answer question pair i.e. for Q.57 and Q.59, 2/3 mark will be deducted for each wrong answer.

QUALIFYING SCORE

Qualifying Score

The Qualifying Score is the minimum mark that needs to be secured to become eligible for availing assistantships provided by MHRD, GOI. The qualifying score for general category in each paper is (a + s) or 25, whichever is higher, where a and s are the average and standard deviation of marks of all candidates in a particular paper, with all marks less than zero, converted to zero..

GATE SCORE

GATE score

The GATE score is calculated using a specific formula, where the marks obtained by the candidate, average of marks of all candidates in that paper, standard deviation of marks of all candidates in that paper, global average of marks of all candidates in last 2 years and the standard deviation (global) of marks of all candidates in last 2 years are considered.
The GATE score is set to zero if the value calculated by the formula is less than zero and the GATE score is set to 1000 if the value calculated by the formula is more than 1000.

ELIGIBILITY FOR GATE

ELIGIBILITY FOR GATE

The following categories of candidates are eligible to appear in GATE :

1. Bachelor degree holders in Engineering/ Technology/ Architecture (4 years after 10+2) and those who are in the final or pre-final year of such programmes.
   
2. Master degree holders in any branch of Science/ Mathematics/ Statistics/ Computer Applications or equivalent and those who are in the final or pre-final year of such programmes.
   
3. Candidates in the second or higher year of the Four-year Integrated Master degree programme (Post-B.Sc.) in Engineering/ Technology or in the third or higher year of Five-year Integrated Master degree programme and Dual Degree programme in Engineering/ Technology.
   
4. Candidates with qualifications obtained through examinations conducted by professional societies recognised by UPSC/AICTE (e.g. AMIE by IE(I), AMICE(I) by the Institute of Civil Engineers (India)-ICE(I)) as equivalent to B.E./B.Tech. Those who have completed section A or equivalent of such professional courses are also eligible.

ABOUT GATE

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 Coordination Board - GATE, Department of Higher Education, Ministry of Human Resource Development (MHRD), Government of India.

The GATE committee, which comprises of representatives from the administering institutes, is the sole authority for regulating the examination and declaring the results.

GATE is conducted through the constitution of eight zones. The zones and the corresponding administrative institutes are:

      Zone-1: Indian Institute of Science Bangalore
      Zone-2: Indian Institute of Technology Bombay
      Zone-3: Indian Institute of Technology Delhi
      Zone-4: Indian Institute of Technology Guwahati
      Zone-5: Indian Institute of Technology Kanpur
      Zone-6: Indian Institute of Technology Kharagpur
      Zone-7: Indian Institute of Technology Madras
      Zone-8: Indian Institute of Technology Roorkee

Admission to postgraduate programmes with MHRD and some other government scholarships/ assistantships in engineering colleges/institutes is open to those who qualify through GATE. GATE qualified candidates with Bachelor’s degree in Engineering/ Technology/ ArchItecture or Master’s degree in any branch of Science/ Mathematics/ Statistics/ Computer Applications are eligible for admission to Master/Doctoral programmes in Engineering/ Technology/ Architecture as well as for Doctoral programmes in relevant branches of Science with MHRD or other government scholarships/ assistantships. To avail the scholarship, the candidate must secure admission to such a postgraduate programme, as per the prevailing procedure of the admitting institution. However, candidates with Master’s degree in Engineering/ Technology/ Architecture may seek admission to relevant PhD programmes with scholarship/ assistantship without appearing in the GATE examination.

Some institutions specify GATE qualification as mandatory 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. Top rank holders in some GATE papers are entitled to apply for “Shyama Prasad Mukherjee Fellowship” awarded by CSIR. Some government organizations prescribe GATE qualification as a requirement for applying to the post of a Scientist/ Engineer.
