JEE Advanced 2023: Subject wise exam analysis, marking scheme here

On Sunday, June 4, 2023, the highly anticipated Joint Entrance Examination (JEE) Advanced exam was successfully conducted by the Indian Institute of Technology (IIT) Guwahati. This year, the exam was held in two phases, with Paper 1 taking place from 9 am to 12 pm and Paper 2 from 2:30 pm to 5:30 pm. Both papers consisted of four sections and were each worth 180 marks, making the total exam worth 360 marks. According to student feedback on the CSAT App, specially designed by ALLEN Career Institute, the difficulty level of both Paper 1 and Paper 2 was comparable, with a general consensus that both papers were challenging. However, some students found Paper 1 to be more difficult to solve.

Physics, one of the subjects tested in the JEE Advanced exam, was reported to be easier than the previous year. Meanwhile, the Mathematics paper was deemed lengthy and difficult, similar to the previous year’s exam. The Chemistry paper remained consistent in terms of difficulty level compared to the previous year. Students who had dedicatedly practiced solving papers of varying difficulty levels and had prepared for the exam throughout the year may have found it relatively easier to tackle the test. Notably, new topics were included in the exam, and despite the removal of the Solution of Triangle topic from the syllabus, two questions were presented in the form of a comprehension. Additionally, Organic Chemistry received slightly higher weightage, and questions from Chemistry in Everyday Life, a newly added topic in the JEE Advanced syllabus, were included in the Organic Chemistry section.

Students who appeared for the JEE Advanced exam can expect to receive their recorded response sheets on June 9 at 5 pm. Subsequently, the provisional answer key will be released on June 11 at 10 am, allowing students to raise objections until 5 pm on June 12. The final answer key, along with the JEE Advanced results, will be announced on June 18.

Subject-wise Analysis:

Physics:
Overall, the difficulty level of Physics in both Paper 1 and Paper 2 was moderate. This year, questions were introduced on newly added topics in the JEE Advanced syllabus, such as Polarization and EM Waves. Furthermore, a question similar to the fluid dynamics question from the previous year’s exam was also included in this year’s test.

Chemistry:
The Chemistry section, in general, was rated as moderate to difficult. Almost all the topics were covered in both Paper 1 and Paper 2. Organic Chemistry received slightly higher weightage, and questions from Chemistry in Everyday Life, which is a new addition to the syllabus, were included in the Organic Chemistry segment. In Inorganic Chemistry, questions were asked from various core topics. In Physical Chemistry, students encountered challenging numerical questions.

Mathematics:
Paper 1 of the Mathematics section proved to be difficult and lengthy, while Paper 2 was of a moderate level but still lengthy. Both papers included questions from Functions, Matrices, Permutation and Combination, Conic Section, Probability and Statistics, Complex Numbers, Vector and 3-D Geometry. Calculus had a relatively lower number of questions compared to previous years. Although the Solution of Triangle topic was removed from the syllabus, two questions were presented in the form of a comprehension.

Marking Scheme:

Paper 1:
The total marks for Paper 1 were 180, and it consisted of 51 questions. Each subject (Physics, Chemistry, and Mathematics) had 17 questions. Paper 1 included four single-correct questions, each worth three marks for a correct answer and a penalty of one mark for an incorrect response. It also had three multiple-correct questions, with four marks for each correct answer and a deduction of two marks for each incorrect answer. The paper contained six numerical and integer type questions, with four marks awarded for a correct answer and no negative marking for wrong answers. Additionally, four questions followed a “match the column” format, akin to single-correct questions. In this section, students received three marks for a correct answer and faced a penalty of one mark for an incorrect response.

Paper 2:
Similar to Paper 1, Paper 2 was also worth 180 marks and consisted of 51 questions. The distribution of questions among subjects was the same as in Paper 1. Four single-correct questions were included in this paper, with three marks for a correct answer and a deduction of one mark for an incorrect response. Three multiple-correct questions were also present, each carrying four marks for a correct answer and a penalty of two marks for an incorrect answer. Two paragraphs were provided, with two questions accompanying each paragraph. Students received three marks for each correct answer, and there was no negative marking for wrong responses. Additionally, six non-negative integer type questions were included, with four marks awarded for a correct answer and no negative marking for incorrect responses.

With the JEE Advanced exam now complete, students eagerly await the release of their recorded response sheets on June 9, followed by the provisional answer key on June 11. The final answer key and results will be announced on June 18.

In conclusion, the JEE Advanced exam conducted by IIT Guwahati on June 4, 2023, presented students with a challenging test that required a comprehensive understanding of the subjects. The difficulty level of both Paper 1 and Paper 2 was considered to be on par, with some students finding Paper 1 to be more difficult. Physics was relatively easier this year, while Mathematics remained long and challenging. Chemistry had a mix of topics, with Organic Chemistry receiving slightly higher weightage and questions from the newly added topic of Chemistry in Everyday Life.

The inclusion of new topics in the exam reflected the evolving syllabus of JEE Advanced, with questions on subjects like Polarization and EM Waves in Physics. Despite the removal of Solution of Triangle from the syllabus, two questions were cleverly incorporated through a comprehension passage. Students who had prepared diligently throughout the year and practiced solving papers of varying difficulty levels were at an advantage.

The marking scheme of the exam consisted of single-correct, multiple-correct, numerical and integer type, and “match the column” questions. Negative marking was applied for incorrect responses in most sections, except for the numerical and integer type questions, which had no negative marking. This highlighted the importance of accurate and thoughtful answering strategies.

Looking ahead, students can anticipate receiving their recorded response sheets on June 9, followed by the provisional answer key on June 11. This will allow them to raise objections if necessary. The final answer key and results of the JEE Advanced exam will be announced on June 18, providing students with the outcome of their hard work and determination.

Overall, the JEE Advanced exam of 2023 was a rigorous assessment that tested students’ knowledge and problem-solving abilities. It serves as a crucial milestone for those aspiring to secure admissions in prestigious Indian Institutes of Technology. The analysis of the difficulty level and subject-wise review provides valuable insights into the exam, helping students understand their performance and identify areas for improvement.
