Imformation About JEE

There are sixteen IITs at present, located at Bhubaneswar, Chennai, Delhi, Gandhinagar, Guwahati, Hyderabad, Indore, Jodhpur, Kanpur, Kharagpur, Mandi, Mumbai, Patna, Ropar, Roorkee and Varanasi. Indian School of Mines(ISM), Dhanbad. The Joint Entrance Examination (Advanced)-2015 will be conducted by seven zonal IITs under the directives of the Joint Admission Board (JAB) for admission to the undergraduate programmes in all IITs and ISM Dhanbad. JEE (Main)-2015 will be conducted by CBSE on behalf of the JEE Apex Board on April 04, 2015 (Offline mode).

The Joint Entrance Examination (Advanced) 2015 [JEE (Advanced) 2015] will be conducted by the seven zonal Indian Institutes of Technology (IITs) under the guidance of the Joint Admission Board (JAB) 2015. The performance of a candidate in this examination will form the basis for admission to the Bachelor's, Integrated Master's and Dual Degree programs (entry at the 10+2 level) in the sixteen IITs and the Indian School of Mines (ISM). The decisions of the JAB 2015 will be final in all matters related to JEE (Advanced) 2015 and admission to IITs and ISM.

The JEE (Advanced)-2015 will be held on Sunday, May 24, 2015 as per the schedule given below: Paper 1:    09:00 to 12:00 hrs (IST)
Paper 2:    14:00 to 17:00 hrs (IST)

Note:       Architecture Aptitude Test (AAT) for B. Arch: June 26, 2014
Both the papers are compulsory.

• Candidates using the SERVICES OF A SCRIBE will get one hour compensatory time i.e., the end time will be 13:00 IST for Paper 1 and 18:00 IST for Paper 2.
• The schedule will remain the same even if the above day is declared a public holiday.

In JEE (Advanced)-2015, there will be two papers, each of three hours duration. The questions will be of objective (multiple choice) type. Candidates will be provided with a two page doublet of optical response sheet (ORS) for answering. Candidates are directed to use black ball point pen only to darken the bubble(s) given as choices of answers to the questions.

The candidate should be among the top 1,50,000 (all categories included) in JEE (Main) 2015. The percentages of the total number of candidates for various categories is as follows:

50.5% for GEN (from the common merit list), 27% for OBC-NCL, 15% for SC and 7.5% for ST. Within each of these four categories, 3% horizontal reservation is available for PwD candidates.

The category-wise distribution of the number of “top” candidates is shown in the following table:

Category-wise distribution of “top” candidates

The candidate should have been born on or after October 1, 1990 if belonging to the GEN or OBC-NCL category and on or after October 1, 1985 if belonging to the SC, ST or PwD category

A candidate can attempt JEE (Advanced) a maximum of two times and that too in consecutive years. Therefore, JEE (Advanced) 2015 should be either the candidate’s FIRST attempt OR the SECONDconsecutive attempt.

The candidate should NOT have taken admission (irrespective of whether or not he/she continued in the program) OR even accepted admission by paying admission fee at any of the IITs or ISM in the past; even candidates whose admission was cancelled are NOT eligible. However, candidates who have been admitted to a preparatory course in any of the IITs in 2014 can appear for JEE (Advanced) 2015.

Admission to IITs and ISM Dhanbad will be based only on category wise All India Rank (AIR) in JEE (Advanced)-2015 subject to the condition that such candidates are among the top 20 percentile of successful candidates of their Boards in respective categories. PwD candidates will be given relaxation in the eligibility criteria as per the decision of the Joint Admission Board of JEE (Advanced)-2015 in consonance with the directives of the Government of India.

In case a Board does not provide the information regarding the cut-off for top 20 percentile of successful candidates in respective category, the candidate will have to produce a certificate from the concerned Board stating that he/she falls within the top 20 percentile of successful candidates. If the candidate fails to do so, then the CBSE percentile will be used as the criteria for deciding minimum cut off marks in qualifying examination.

Candidates who passed their QE in 2014 will be considered on the basis of the top 20 percentile cut off marks of their boards in 2014. Candidates, who passed in 2014 and would improve their performance of QE in 2015, will be considered on the basis of 2015 cut off marks of their respective Boards in their respective category.

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 online acceptance of seat.

• All the sixteen IITs and ISM run preparatory courses of one year duration for SC, ST and PwD candidates.
• In case the seats reserved for SC, ST and PwD candidates are not filled completely, a limited number of candidates are admitted to a preparatory course of one-year duration on the basis of further relaxation of admission criteria Merit lists.
• 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.
• On successful completion of the course, the students will be offered direct admission in July 2016 (Academic Year 2016-17) to the already allotted undergraduate course.
• Candidates admitted to the preparatory course are also eligible to appear for JEE (Advanced) 2016 subject to fulfilling other eligibility criteria.
• Filling-in of choices for preparatory courses is also through the same online portal.

Defence Service (DS) category candidates are children of defence / paramilitary personnel killed or permanently disabled in action during war or peacetime operations. Two seats are available for preferential allotment in each Institute for DS category candidates. To avail of this preferential allotment, a DS category candidate must be in the Common Merit List of JEE (Advanced) 2015

• Display of ORS image and scanned responses:

• Request from candidates for review of their scanned responses:

• Display of answer keys:

• Receiving feedback from candidates on answer keys:

• Display of marks allotted:

• Results of JEE (Advanced) 2015:

• Only candidates who appear for both Paper 1 and Paper 2 will be considered for ranking.
• The marks obtained by a candidate in Physics in JEE (Advanced) 2015 will be equal to the marks scored in Physics part of Paper 1 plus the marks scored in Physics part of Paper 2. Marks obtained in Chemistry and Mathematics will be calculated in the same way.
• The aggregate marks obtained by a candidate in JEE (Advanced) 2015 is the sum of the marks awarded to him/her in Physics, Chemistry and Mathematics.
• Merit lists will be prepared based on the aggregate marks in JEE (Advanced) 2015.
• If the aggregate marks scored by two or more candidates are same, then the following tie-break policy will be used for awarding ranks:
  Higher rank will be assigned to the candidate who has obtained higher marks in Mathematics. If this does not break the tie, higher rank will be assigned to the candidate who has obtained higher marks in Physics. If there is a tie even after this, candidates are assigned the same rank.
• Merit lists for preparatory courses will be prepared only if the number of SC, ST and PwD candidates in the respective merit lists is less than 1.4 times the number of seats available in the respective categories.
• A candidate who qualifies in more than one category will be considered in all the categories to which he/she belongs for the purpose of ranking.
• There will be no waiting list for ranking.
• Only candidates who score the minimum prescribed marks in each subject in each paper and in aggregate will be included in the merit list. The minimum prescribed marks varies with the category. These are as shown in the following table.

Separate merit lists will be prepared for preparatory courses only if the number of SC/ST/PwD candidates in the respective merit lists is less than 1.4 times the number of seats available in the respective categories. To be in these merit lists, candidates must score at least 2.5% in each subject and 8.75% in aggregate.

The tie-break policy in the various merit lists adopted for awarding ranks to the candidates who have scored the same aggregate marks is as follows: Higher rank will be assigned for higher marks in Mathematics, followed by marks in Physics and Chemistry. Candidates securing same marks in all these three subjects will be assigned the same rank.

Note: Obtaining a rank in JEE (Advanced)-2015 does not guarantee admission to any of the courses available at IITs, and ISM Dhanbad.

• Candidates desirous of joining the B. Arch. (Architecture) courses will have to PASS in the Architecture Aptitude Test (AAT). Only those candidates who have secured an all India / category rank in JEE (Advanced) 2015 are eligible to appear for AAT in 2015.
