IIT-JEE 2012 was conducted on April 8, 2012 in 1067 centres all over India. This year’s JEE had two tests of 60 marks each, having questions from mathematics, physics and chemistry with 20 questions from every subject. Here’s a paper-wise analysis of the exam.
Paper I for IIT-JEE 2012 saw some minor deviations from the pattern as compared to the last couple of years. This edition featured 20 questions each in physics, chemistry and mathematics with only three sections per subject (or part). Section 1 featured 10 multiple choice type questions with only a single option to be chosen, section 2 featured five multiple choice questions with more than a single option to be chosen and section 3 had five questions of the ‘integer answer type’ variety.
Initial analysis indicates that the question set was well-balanced featuring questions distributed from the entire syllabi with more emphasis on conceptual clarity and application of fundamentals.
Physics: Other than a couple of sections such as gravitation and simple harmonic motion which were omitted, the question set featured a balanced approach to the syllabus. Also the emphasis was more on application of concepts rather than lengthy calculations.
Chemistry: This was ‘neither difficult nor easy’. Equal weightage was given to organic, inorganic and physical chemistry. The emphasis on different topics and the types of problems related well with the content arrangement in NCERT books.
Mathematics: This section stood out in comparison to the others as it was slightly lengthier. While there were hardly any lengthy calculations required, the problems did require sufficient time for analysis. There seemed to be more focus on calculus, vectors and 3D coordinate geometry sections. As far as paper I is concerned, mathematics might turn out to be the deciding factor.
Paper 2 for IIT-JEE 2012 was tougher than the first paper and more tricky as well. It also featured a structural change as compared to the last two editions of the exam. This time each part featured three sections each with section I containing eight multiple-type questions with only one option to be selected, section 2 containing three paragraph-type questions with two questions per paragraph (therefore a total of six questions) and section 3 containing six multiple choice questions with more than one option to be selected.
The question sets again had more emphasis on concepts as opposed to questions requiring extremely lengthy solving.
Physics: Paper 2 was trickier as compared to paper 1 with some interesting questions in mechanics in particular.
Chemistry: Subject experts have rated the chemistry section for paper 2 to be relatively easy in comparison to paper 1. Overall, the questions focus more on conceptual understanding and there is a high correlation with the NCERT curriculum. Also, the chemistry parts of both papers 1 and 2 featured few technical ambiguities compared to previous years.
Mathematics: This section should not have presented any major hiccups to well-prepared students. Neither were the questions conceptually tricky and nor were they lengthy.
