Paper Analysis of JEE (Advanced) - (2013)

JEE (Advanced) - (2013) Paper-1 Analysis

Overall the paper quality was good. The JEE body offered a well deserved paper to its aspirants. In terms of changes from last year, there has been a change in marking scheme. This year, the section with single correct answer has no negative marking while the section with multiple correct type MCQ has negative marking which makes the paper tough.

If we talk about the Physics section of JEE advanced 2013 Paper-I, it was of medium intensity. There were a few traps to entice a student to commit mistakes and mark the wrong answers. A student with a balanced state of mind, who reads each and every word carefully, would do well in this paper. For example, there were 3 questions, which were presented in a way that a student could get the wrong answer if he did not read them carefully. And the wrong answers were also there in the choices. Out of 20 questions in the Physics section, 3 were of very easy level, 2 were of hard level and remaining was of medium level. The average score would around 35 out of a total of 60.

The Chemistry section of JEE (Advanced) 2013 Paper-I had thought provoking questions. Some of the questions are very tricky and required in depth knowledge. The average student is more likely to commit mistake in such questions. Majority of the problems were straight forward. Many of average and above average students are likely to attempt these problems correctly. Out of 20 problems, 4 problems were of easy level, 10 problems were of moderate and 6 problems were of difficult level. The average score would be around 30 out of a total of 60.

Finally, like always the mathematics section remains the deciding section of the IIT entrance. This year also the JEE Advanced 2013 Paper-I of Maths was of relatively tough level, as compared to Physics & Chemistry. There were at least 8 to 10 questions out of 20 questions, in which students can commit mistake in very easy way. Most of the questions are from mixed concepts and taking very more than expected time for finding accurate (exact) answer. Paper is relatively lengthy, but was balanced with respect to weightage of class XI and XII portion. The questions from class XI topic were of complicated nature and would have required fair amount of effort from the student’s end to get exact solution. The major effect of Paper-I was that very first time JEE has introduced negative marking on multiple choice questions and integer type questions that makes the paper tough. The average score in this section should be around 24 out of a total of 60.

JEE (Advanced) - (2013) Paper-2  Analysis

The overall level of Paper – 2 of JEE (Advanced) was also very good. Here, unlike Paper-1, the Physics & Chemistry sections were of high order. In fact, the Paper-2 had a few surprises in terms of the pattern of the questions asked. Firstly, the first section in each of the subjects had 8 questions of multiple-answer type. This change in pattern made the paper lengthier, since it require more time to solve questions with more than one correct answer. Secondly, the paper also introduced, Match the column type questions for the first time. Also, the comprehension type questions were also more in number as compared to previous year’s papers.
If we talk about Physics, the Paper-2 was lengthy and difficult in comparison to Paper-1. The overall level of questions in Physics was not difficult, but students found the language of questions asked quite difficult. The average score in this part would be around 24.

With respect to the Chemistry section of Paper-2, it was relatively more difficult than Paper-1. Many of the problems were based on reaction mechanisms. Any student who was not well versed with reaction mechanism could not have been able to answer such questions. Some of the questions from Inorganic Chemistry were innovative in nature and required high caliber to crack them. Out of 20 questions, 6 questions were easy, 6 questions were moderate and remaining 8 questions were of difficult level. The cut-off of this paper is expected to be around 24 out of 60 marks i.e., 40%.

Finally the Mathematics section of Paper-2 was easy but overall quite lengthy to solve. Like other two sections, here also 8 multiple answer questions created problem for students. 9 questions were from class XI syllabus and 11 questions were from XII potion. Overall Maths section was of medium level in Paper-2. The cut-off marks can be expected to be around 25 out of 60.


Marking Scheme of JEE (Advanced) - 2013


JEE (Advanced): Paper-1

Question Paper Format
The question paper consists of three parts (Physics, Chemistry and Mathematics). Each part consists of three sections.
Section 1 contains 10 multiple choice questions. Each question has four choices (A), (B), (C) and (D) out of which ONLY ONE is correct.
Section 2 contains 5 multiple choice questions. Each question has four choices (A), (B), (C) and (D) out of which ONE or MORE are correct.
Section 3 contains 5 questions. The answer to each question is a single-digit integer, ranging from 0 to 9 (both inclusive).

Marking Scheme
For each question in Section 1, you will be awarded 2 marks if you darken the bubble corresponding to the correct answer and zero mark if no bubbles are darkened. No negative marks will be awarded for incorrect answers in this section.
For each question in Section 2, you will be awarded 4 marks if you darken all the bubble(s) corresponding to only the correct answer(s) and zero mark if no bubbles are darkened. In all other cases, minus one (–1) mark will be awarded.
For each question in Section 3, you will be awarded 4 marks if you darken the bubble corresponding to only the correct answer and zero mark if no bubbles are darkened. In all other cases, minus one (–1) mark will be awarded.


JEE (Advanced): Paper-2 

Question Paper Format
The question paper consists of three parts (Physics, Chemistry and Mathematics). Each part consists of three sections.
Section 1 contains 8 multiple choice questions. Each question has four choice (A), (B), (C) and (D) out of which ONE or MORE are correct.
Section 2 contains 4 paragraphs each describing theory, experiment, data etc. Eight questions relate to four paragraphs with two questions on each paragraph. Each question of a paragraph has ONLY ONE correct answer among the four choices (A), (B), (C) and (D).
Section 3 contains 4 multiple choice questions. Each question has matching lists. The codes for the lists have choices (A), (B), (C) and (D) out of which ONLY ONE is correct.

Marking Scheme
For each question in Section 1, you will be awarded 3 marks if you darken all the bubble(s) corresponding to only the correct answer(s) and zero mark if no bubbles are darkened. In all other cases, minus one (-1) mark will be awarded.

For each question in Section 2 and 3, you will be awarded 3 marks if you darken the bubble corresponding to only the correct answer and zero mark if no bubbles are darkened. In all other cases, minus one (-1) mark will be awarded.
