Indian Institutes of Technology or IIT’s as they are popularly known, are the Nation’s premier institutes for Engineering studies.
Each year several tens of thousands of students attempt to make the cut to claim these ‘Creme de la creme’ of Engineering seats. IIT’s Joint Entrance Examination-JEE, is one of the hardest Engineering entrance exams to crack but the rewards are sure worth your efforts.
Indian Institutes of Technology conduct IIT-JEE every year for the admission to its B-Tech and other courses offered at IIT Kharagpur, IIT Mumbai, IIT Chennai, IIT Kanpur, IIT Delhi, IIT Guwahati, IIT Roorkee, IIT Bhubaneswar, IIT Gandhinagar, IIT Hyderabad, IIT Patna, IIT Punjab, IIT Rajasthan and ISM (Dhanbad
Eligibility for IIT-JEE
Candidates must make sure that they satisfy all the eligibility conditions given below for appearing in IIT-JEE
Age : not more than 24 years
Year of Passing Qualifying Examination (QE)
The year of passing the QE will be determined based on the examination he/she passed the earliest out of the qualifying examinations listed below. In case the applicant passed more than one QE or attempted successfully same QE more than once, the year of the first successful QE/attempt will be used to determine the eligibility for IIT-JEE.
The qualifying examinations are listed below:
In case the relevant QE is not a public examination, the candidate must have passed at least one public (Board or Pre-University) examination at an earlier level.
Minimum Percentage of Marks in QE
Candidates belonging to GE and OBC categories must secure at least 60% marks in aggregate in QE. SC, ST and PD candidates must secure at least 55% marks in aggregate in QE.
The percentage of marks awarded by the Board will be treated as final. If the Board does not award the percentage of marks, it will be calculated based on the marks obtained in all subjects listed in the mark sheet. If any Board awards only letter grades without providing an equivalent percentage of marks on the grade sheet, the candidate should obtain a certificate from the Board specifying the equivalent marks, and submit it at the time of counselling / admission. In case such a certificate is not provided the decision taken by the Joint Implementation Committee (JIC) of IIT-JEE will be final.
Number of JEE Attempts
A candidate can attempt JEE maximum two times in consecutive years irrespective of whether or not he/she passed QE.
Earlier Admission Taken Through JEE
Candidates who have taken admission (irrespective of whether or not they continued in any of the programmes) or accepted the admission by paying the registration fee at any of the IITs, IT-BHU Varanasi or ISM Dhanbad, are NOT ELIGIBLE to appear in IIT-JEE
The offer of admission is subject to verification of original certificates/ documents at the time of admission. If any candidate is found ineligible at a later date even after admission to an Institute, his/her admission will be cancelled.

There will be two question papers, each of three hours duration. Both the question papers will consist of three separate sections on Physics, Chemistry and Mathematics. The questions will be of objective type, designed to test comprehension, reasoning and analytical ability of candidates.
The answers for each of the questions are to be marked on a separate, specially designed, machine-gradable sheet of paper (ORS – Optical Response Sheet). While answering each of the questions the candidate is expected to darken the bubble(s) against correct answer(s) using black ball point pen only. In some sections, incorrect answers may be awarded negative marks.
Reservation of Seats
As per Government of India rules candidates belonging to certain categories are admitted to seats reserved for them based on relaxed criteria. Benefit of reservation shall be given only to those classes/castes/tribes which are in the respective central list published by the Government of India.
For the SC and ST categories, 15% and 7.5% seats, respectively, are reserved in every programme in all IITs, IT-BHU Varanasi and ISM Dhanbad. Candidates belonging to these categories are declared qualified on the basis of a relaxed criterion.
Candidates belonging to SC/ST categories will be required to produce the original caste/ tribe certificate issued by a competent authority in the prescribed format during admission. Certificates in any other format will not be accepted. Seats remaining vacant in these categories shall not be filled by candidates belonging to any other category.
For the purpose of reservation of seats in IIT-JEE a candidate will be considered as OBC only if he/she belongs to the non-creamy layer of this category. Those belonging to the creamy layer of OBC are NOT entitled for reservation.
For candidates belonging to OBC (non creamy layer), 27% of the seats are reserved in all IITs, IT-BHU Varanasi and ISM Dhanbad.
In case the reserved seats in this category are not filled, they can be filled by GE category candidates.
The OBC candidates (non-creamy layer) will be required to produce original OBC(NCL) caste certificate by a competent authority in the prescribed format at the time of admission. Certificates in any other format will not be accepted.
Physically Disabled (PD)
In each institute 3% of seats in every category are reserved for PD candidates. For any category of disability (viz., locomotor, visual, dyslexia, speech, and/or hearing) benefit would be given to those who have at least 40% physical impairment. Leprosy-cured candidates who are otherwise fit to pursue the course are also included in this category. Candidates belonging to this category are qualified on the basis of a relaxed criterion.
The percentage of disability of the candidates will be required to be certified by a medical board constituted by IITs. The decision of the medical board would be final.
In case the seats reserved for SC/ST/PD candidates are not filled, a limited number of candidates are admitted to a Preparatory Course of one-year duration on the basis of a further relaxation of admission criteria. Admission is given to the candidates in the preparatory course provided (i) the seats reserved for the respective category are vacant (ii) candidates satisfy minimum norms, and (iii) candidates have not undergone the Preparatory Course earlier.

IIT JEE Tips
The Indian Institute of Technology – Joint Entrance Examination (IIT-JEE), bears a significant fame, as it acts as the dream gate of entrance to the seventeen IIT’s in India. Cracking IIT-JEE is not that easy, as it approves quality inflow of students, based on merits. Hence, it sets the question paper with a high standard of quality to assure consistent quality results.
A survey result describes that out of 384, 977 candidates appeared for the IIT-JEE on April 12, 2009, only 10, 035 candidates were declared qualified for the admissions. At the same time, it is not that scary, as it appears to be! An energetic blend of hard work; confidence; quality preparation; clear planning and implementation of problem solving strategies, along with passion would fetch good results on one’s hands!
