1 IIT-JEE 2012 Pattern and Analysis IIT-JEE, the most challenging of the Engineering Entrance exams in the country; probably conducted for the last time (since from 2013 we are looking forward to ISEET), it has not lost its charm at all and has retained its glory as ever. IIT-JEE 2012 was conducted on 8 th April 2012 in 1067 centres with about 5.06 lakh candidates. Paper 1 was from hrs and paper 2 from to hrs. For the first time, the aspirants could use only a Black Ball Point pen on the OMR sheet and JEE permitted students to carry a copy of their OMR sheets with them as they walk out of the examination hall. Answer key to the JEE 2012 questions will be displayed on the JEE website after 7 th May, There were 10 versions for IIT-JEE to 9. The order of subjects in both papers were the same Physics, and Mathematics and but the total marks, the number of questions and types of questions in both papers were distinct from each other. Paper 1 Paper1 had 60 questions in total for 210 marks - in the order of Physics, and Mathematics. Each subject had 20 questions and the pattern was exactly the same for all the subjects. Type of question Number of questions Marks for a correct answer Negative marking Total Marks for the Section Section I - Single Correct Answer Type Section II - Multiple Correct Answers Type 5 4 NIL 20 Section III - Integer Answer Type 5 4 NIL 20

2 Part 1 - Physics Physics part of paper 1 of the IIT-JEE 2012 was commented to be a comfortable paper for the aspirants even though a few questions involved tedious calculations. Integration of concepts across the topics was not reflected in majority of the questions; this was one reason which made this paper easier. One may note as given below about 50 % of the Physics of paper 1 is categorized as. PHYSICS - PAPER I - y Analysis 33% 1 4 The topic wise distribution of the questions is shown below: PHYSICS - PAPER I - Topic wise Analysis 4% 6% 48% Electricity & Magnetism Heat & thermodynamics Mechanics Modern Physics 24% General Physics Optics

3 Part 2 of Paper 1 of IIT-JEE 2012 contains questions of moderate difficulty level. More emphasis was to Physical and Organic portions and only a very nominal representation was given to Inorganic. As given below about 50% of the paper was considered and hence this was a student friendly paper. CHEMISTRY - PAPER I - y Analysis 10% 4 41% The topic wise analysis of paper 1 for is shown below. CHEMISTRY - PAPER I - Topic wise Analysis 46% 14% Inorganic Organic 40% Physical

4 Part 3 Mathematics Mathematics part of paper 1 of IIT-JEE 2012 was a moderately difficult paper that involved both algebraic manipulations and in-depth subject knowledge. One particular question in Integral inequality was tricky since the aspirants might know only the standard results. With only 30% of the marks under the easy category, this is a challenging paper. MATHEMATICS - PAPER I - y Analysis 36% 30% 34% Calculus, Algebra and Coordinate Geometry had major shares but the other areas were also well represented. Topic wise analysis is given below. MATHEMATICS - PAPER I - Topic wise Analysis Algebra 6% 14% 20% Coordinate Geometry Differential Calculus Integral Calculus Trigonometry 16% 24% 20% Vectors, 3-D, Matrices & Determinants

5 Paper 2 Paper 2 had 60 questions in total - in the order of Physics, and Mathematics. Each subject had 20 questions and as in paper 1 the pattern was exactly the same across the subjects. All Single correct questions had 3 marks for a correct answer whereas Multiple correct questions had 4 marks, each subject had 66 marks and the maximum mark for the paper was 198. Type of question Number Marks for Total Negative of a correct Marks for marking questions answer the Section Section I - Single Correct Choice Type Section II - Paragraph Type Section III Multiple Correct answers Type 6 4 NIL 24 Part 1 - Physics Physics part of paper 2 of the IIT-JEE 2012 was more difficult than paper 1. There was an ambiguity about the shaded portion in one of the single correct answer type questions (Qn.4 in version 0). In general comprehension based (paragraph type) questions were perceived as difficult by the students especially questions using concepts from Rotational Dynamics (Qn. 13 & 14 in version 0) The difficulty analysis and the topic wise analysis are shown below:

6 PHYSICS - PAPER 2 - y Analysis 23% 15% 62% PHYSICS - PAPER 2 - Topic wise Analysis Electricity & Magnetism 5% 32% Heat & thermodynamics Mechanics Modern Physics Properties of Matter 40% 5% Optics Part 2 part of Paper 2 of IIT-JEE 2012 was considered difficult compared to paper 1. More in-depth knowledge was necessary to solve many questions of this paper. There was one question (Qn.22 in version 0) that contained a likely improbable answer.

7 33% CHEMISTRY - PAPER 2 - y Analysis 14% 53% Representation of Inorganic in paper 2 compensated for the lesser representation of the same in paper 1. CHEMISTRY - PAPER 2 - Topic wise Analysis 35% 35% Inorganic Organic 30% Physical Part 3 Mathematics Mathematics part of Paper 2 IIT-JEE 2012 was a hairline easier than paper 1. Though there were quite a number of questions to choose from, some of the questions were time consuming. Comprehension in Algebra on number theory was difficult from the student point of view and one might not reach to prove the hypothesis in a direct way.

8 MATHEMATICS - PAPER 2 - y Analysis 11% 45% 44% Algebra had a major share compared to Calculus. The topic wise distribution is shown below: MATHEMATICS - PAPER 2 - Topic wise Analysis Algebra 11% 15% 3 Coordinate Geometry Differential Calculus Integral Calculus Trigonometry 17% Vectors, 3-D, Matrices & Determinants
