IIT JAM Marking Scheme
The IIT JAM 2025 marking scheme is meticulously designed to assess candidates’ knowledge, problem-solving abilities, and conceptual understanding. The exam is conducted for a total of 100 marks, and candidates are given 3 hours to complete the test. The paper is divided into three sections to evaluate candidates comprehensively:
Section A: This section includes 30 Multiple Choice Questions (MCQs):
10 questions carry 1 mark each.
20 questions carry 2 marks each.
A negative marking system applies in this section. For each incorrect 1-mark question, 1/3 mark is deducted, and for each incorrect 2-mark question, 2/3 mark is deducted.
Section B: This section features 10 Multiple Select Questions (MSQs), each worth 2 marks. Candidates are required to select more than one correct answer where applicable.
There is no negative marking in this section, allowing candidates to attempt these questions without any penalties.
Section C: This section includes 20 Numerical Answer Type (NAT) questions, which test candidates’ ability to solve problems and provide numerical solutions.
10 questions are worth 1 mark each.
10 questions are worth 2 marks each.
Like MSQs, this section has no negative marking, giving candidates more flexibility to attempt questions confidently.
The marking scheme ensures that candidates are evaluated on multiple parameters, including their knowledge, accuracy, and analytical thinking abilities.
IIT JAM Paper Pattern
The JAM 2025 examination is a Computer-Based Test (CBT) conducted entirely in English to ensure standardization. Each test paper consists of a combination of MCQs, MSQs, and NATs, carefully crafted to evaluate the conceptual and analytical strengths of candidates. The duration of the exam is three hours, during which candidates must tackle questions that range from basic recall to complex problem-solving. This well-balanced paper pattern ensures that candidates with strong fundamentals and critical thinking skills perform well. The distribution of questions across three sections is designed to test candidates at various levels of difficulty, fostering a holistic assessment. Additionally, the CBT format provides a seamless testing environment, reducing the likelihood of errors and ensuring uniformity in evaluation. Aspirants must strategize effectively, managing their time across sections while maintaining accuracy to maximize their scores.
IIT JAM Negative Marks and Tie Breaker
Negative marking plays a significant role in Section A of the IIT JAM paper, where incorrect answers can lead to mark deductions. This system emphasizes accuracy and discourages guesswork, making it crucial for candidates to attempt only those questions they are confident about. Sections B and C, however, do not have negative marking, allowing aspirants to attempt these questions without the fear of penalties.
In cases where two or more candidates score the same aggregate marks, a tie-breaking mechanism is employed. The ranking is determined using the following criteria, in order of priority:
Candidates with fewer negative marks are ranked higher.
The total marks obtained in NAT questions are considered next.
If the tie persists, the marks in MSQ questions are compared.
The total marks in 2-mark questions are evaluated subsequently.
If a tie still exists, the score in 2-mark NAT questions is assessed.
As a last resort, the candidate’s date of birth (DOB) is considered, with preference given to the older candidate.
This detailed tie-breaking system ensures fairness and helps identify the most deserving candidates in a competitive scenario.
