Yes, you can analyze your performance in mock tests and practice papers based on the marking weightage to identify areas of improvement for the IIT JAM Mathematics Paper. Here is a detailed explanation of how you can do it:

1. Familiarize yourself with the marking weightage:
- Before starting the analysis, it is important to understand the marking weightage of different topics in the IIT JAM Mathematics Paper.
- Go through the syllabus and previous year papers to get an idea of which topics carry more weightage in the exam.

2. Gather your mock test and practice paper results:
- Collect all your mock test and practice paper results, along with the solutions or answer keys.
- Make sure you have attempted a sufficient number of tests to have a substantial amount of data for analysis.

3. Categorize the questions based on topics:
- Start by categorizing the questions in each test based on the topics they belong to.
- Create a table or spreadsheet with columns for topics and rows for each test.

4. Calculate the percentage of marks obtained in each topic:
- For each test, calculate the percentage of marks obtained in each topic.
- Divide the marks obtained in a particular topic by the total marks for that topic and multiply by 100.

5. Analyze the performance:
- Look for patterns and trends in your performance across different topics.
- Identify the topics where you consistently score low or struggle the most.

6. Prioritize areas of improvement:
- Based on the analysis, prioritize the topics where you need improvement.
- Focus more on topics with higher weightage and those in which you consistently score low.

7. Devise a study plan:
- Create a study plan that allocates more time and effort to the identified areas of improvement.
- Break down the topics into subtopics and allocate specific study sessions for each.

8. Practice and revise:
- Utilize study materials, textbooks, online resources, and EduRev to strengthen your understanding of the identified topics.
- Solve more practice questions and mock tests specifically targeting those topics.

9. Monitor your progress:
- Regularly evaluate your progress by taking more mock tests and practice papers.
- Compare your performance to the previous analysis to track improvements.

10. Repeat the analysis:
- Repeat the analysis of your performance after completing a significant amount of study and practice.
- Identify any new areas of improvement that may have emerged.

By analyzing your performance in mock tests and practice papers based on the marking weightage, you can effectively identify areas of improvement for the IIT JAM Mathematics Paper. This analysis allows you to focus your efforts on the topics that carry more weightage and the ones in which you struggle the most, ultimately enhancing your chances of success in the exam.
