Understanding Your JEE 2021 March Attempt with Official Answer Key

The Joint Entrance Examination (JEE) 2021 March attempt was a crucial milestone for students aiming for top-tier engineering institutions like IITs. The release of the official answer key sparked a wave of anticipation among test-takers for their performance indicators. Let's delve into the details of the scores and expectations shared by students and how these scores can predict their percentile rankings.

Case Study: Achieving 167 Marks in JEE 2021

One student reported a score of 167 marks in the March 16th shift 1. The subject-wise breakdown was as follows:

Physics: 71 Chemistry: 61 Mathematics: 35

Given the toughness of the exam, many students perceived it as the second toughest. Based on this analysis, the student anticipates a percentile in the 98th range, attributing the lower math score to the challenging nature of the exam.

Considering another student's feedback on the tough exam, the second case study is a direct analogy. This student scored 242 marks in the 16th March evening shift, with individual scores of:

Physics: 81/100 Chemistry: 85/100 Mathematics: 75/100

The student believes the exam was the second toughest, aligning with the first report. Upon the official result, the percentile score was 99.91, highlighting the high difficulty and the student's performance.

Accuracy in Calculations: A Case of -113 Degree Celsius

A third student reported a total score of 191 marks, which included:

Physics: 64 Chemistry: 72 Mathematics: 55

A noteworthy issue in the Physics Section B was a heat engine question marked incorrect with an answer of 113-degree Celsius instead of -113 degrees Celsius. If this were corrected, the predicted score would be 195 marks. Considering the challenging nature, this student is optimistic about a 99.3 percentile ranking.

Additional Score Observations

Another set of scores from the 18th March morning shift shows a standout performance of 270 marks. The distribution was:

Mathematics: 78 Physics: 80 Chemistry: 48

Lastly, a student achieved 244 marks in the 18th March morning shift, suggesting similar expectations from the earlier student with the 16th March 18th shift.

These insights underscore the importance of understanding the official answer key thoroughly and the subjective nature of exam scores. The variety in scores across shifts indicates the exam's difficulty level and the individual strengths of the students._PERCENTILE PREDICTIONS: - For 167 marks, a 98th percentile is expected. - For 242 marks, a 99.91 percentile was achieved. - For 191 marks with the correction, an 99.3 percentile is anticipated. - For 270 marks, a very high percentile in the 99.9% range is expected. In conclusion, understanding your score and the official answer key is crucial for evaluating your performance and percentile ranking in the JEE 2021 March attempt. These insights offer valuable guidance for future JEE aspirants, helping them strategize for upcoming exams.
