JEE Advanced 2015 Question Paper Subject-Wise Analysis

JEE Advanced 2015 Mathematics Section Analysis

The JEE Advanced 2015 question paper analysis of the Mathematics section is as follows.

• The majority of questions came from important topics like Coordinate Geometry, Algebra, Calculus, 3-D and Vector Algebra, etc.

• The questions of Mathematics part in Paper I and II were of easy to difficult levels.

• Longer calculations were required for some of the questions.

• Concepts from various areas were included in the Matrix Match type questions.

JEE Advanced 2015 Physics Section Analysis

The JEE Advanced 2015 question paper analysis of the Physics section is as follows.

• Questions were asked from almost all chapters with more weightage to Electrostatics & Magnetism, Modern Physics, Ray Optics, Error & Dimensional Analysis.

• The level of difficulty of Physics questions was considered to be moderate to difficult.

• The questions were designed in a manner that they were testing the student's Maths skills rather than testing conceptual clarity.

• The Physics section was more focused on the syllabus for Class XII.

JEE Advanced 2015 Chemistry Section Analysis

The JEE Advanced 2015 question paper analysis of the Chemistry section is as follows.

• The questions of organic and inorganic chemistry were of a moderate level while difficult questions were asked from Physical Chemistry.

• The level of difficulty of the Chemistry section in paper I and paper II was of moderate level.

• Some of the questions appeared to be a little challenging and required additional time to answer.

Overall Difficulty Analysis of JEE Advanced 2015

The overall analysis of the JEE Advanced 2015 Question Paper is given below.

 Subject Easy Moderate Difficult Number of Questions Total Marks Number of Questions Total Marks Number of Questions Total Marks Physics 11 44 17 68 12 56 Chemistry 9 36 15 60 16 72 Maths 7 28 15 60 18 80 Grand Total 27 108 47 188 46 208

Apart from the difficulty level of the questions asked in the question paper, the pattern of the JEE Advanced 2015 was on the harder edge. It contained Multiple Answers Correct and Numerical Answer-type questions only, with no Single Answer Correct type questions at all. Also, it was claimed that the questions were moderate yet time-consuming. This made the overall paper a bit lengthy to be solved within the provided time constraints.

Marking Scheme in JEE Advanced 2015

The marking scheme of JEE Advanced is quite unique. The marking scheme is discussed below that was followed in the JEE Advanced 2015 Paper I and II.

 Section Paper I Question Pattern Marking Scheme No. of Questions Total Marks 1 Numerical Answer Type +4 for each correct answerNo negative marking 8 32 2 Multiple Answers Correct Type +4 for each correct answer-2 for wrong answer 10 40 3 Matching Columns Type +2 for each of 4 correct answers-1 for each wrong answer 2 16

 Section Paper-II Question Pattern Marking Scheme No. of Questions Total Marks 1 Numerical Answer Type +4 for each correct answerNo negative marking 8 32 2 Multiple Answers Correct Type +4 for each correct answer-2 for wrong answer 8 32 3 Paragraph Type Multiple Answer Correct +4 for each correct answer-2 for each wrong answer 4 16

JEE Advanced total marks 2015 was 504. From the above analysis, it is pretty clear that the marking scheme was a bit different from the other years' papers. The paper consisted of Multiple Answers Correct type and Numerical Answer type questions only. There were no Single Answer Correct type questions in either paper-1 or paper-2. It could also be deduced that the questions carried relatively higher negative markings than usual.

Distribution of Questions of JEE Advanced 2015

The questions in JEE Advanced come from the syllabus of Classes 11th and 12th. The distribution of questions in both Paper I and Paper II is given below:

 Subject Class 11 Class 12 Total Number of Questions Total Marks Number of Questions Total Marks Number of Questions Total Marks Chemistry 13 56 27 126 40 168 Maths 16 72 24 96 40 168 Physics 16 68 24 100 40 168 Grand Total 45 196 75 322 120 504

FAQs on JEE Advanced 2015 Question Paper Analysis

1. Was the JEE Advanced 2015 paper tough?

JEE Advanced 2015 paper was overall moderate in toughness level. The questions were not hard to solve, but at the same time, not very easy either. Although there were reasons for this, students did not score as much as they could have scored according to the difficulty level of the questions asked in the paper. The first reason was the length of the paper. This was observed by most of the candidates that year. The second reason for the relative drop in the score was the pattern of the paper. The paper of JEE Advanced 2015 was framed in one of the toughest formats. It had all multiple-select questions only, and most of the questions had high negative markings. These were the reasons for which the JEE Advanced 2015 paper might be considered to lean more towards the tougher side.

2. What were the full marks of the JEE Advanced 2015 question papers?

The maximum marks of JEE Advanced 2015 papers was 504 in total constituting 264 marks for paper-1 and 240 marks for paper-2. The per subject overall weightage was 168 marks for each of the three subjects (physics, chemistry, and mathematics).

6. How to solve the JEE Advanced 2015 question paper?

The main part of the strategy to be followed to solve most of the questions in the JEE Advanced 2015 question paper is ‘Time Management’. Sit to solve the papers (paper 1 and paper 2) for a 3-hour interval for each. As the paper was lengthy and had mostly moderate-level questions, we should save time wherever possible and be attentive while performing calculations to avoid making calculation errors and recalculating. At the end, compare your answers from the answer keys and go through the solutions provided. This way, you will be able to analyse and compare the approach you gave to the questions with those given in the solutions based on the accuracy and time required to solve them using different methods.

7. What was the mode of the JEE Advanced 2015 question paper?

JEE Advanced 2015 was conducted in both modes (pen and paper mode and computer-based test mode). Until 2017, JEE (Joint Entrance Examination) was conducted by the Central Board of Secondary Education in both ‘Online’ (or Computer-Based Test) mode and ‘Offline’ (or Pen and Paper) mode. Since 2018, the National Test Agency has started conducting JEE and the paper has started to be held in computer-based test mode only.
