Introduction:
When preparing for any competitive exam, it is important to have a well-planned study strategy. One aspect of this strategy is to decide whether to focus on new mock tests or repeat ones that have already been attempted. Both approaches have their own advantages and it is essential to understand them in order to make an informed decision.

1. The Benefits of Focusing on New Mock Tests:
- Exposure to new questions: By attempting new mock tests, you will be exposed to a wider variety of questions. This will help you expand your knowledge and improve your problem-solving skills.
- Simulating real exam conditions: New mock tests can closely simulate the actual exam conditions, allowing you to get accustomed to the time constraints and pressure that you will face on the day of the exam.
- Identifying knowledge gaps: Attempting new mock tests can help you identify areas where you are weak. This will allow you to focus your efforts on improving your understanding of these topics.

2. The Benefits of Repeating Mock Tests:
- Reinforcement of concepts: Repeating mock tests can strengthen your understanding of the concepts covered in the exam. By revisiting the questions you have already attempted, you can reinforce your knowledge and identify any gaps in your understanding.
- Improvement in time management: By repeating mock tests, you can work on improving your time management skills. By analyzing the time taken to solve each question, you can identify areas where you need to speed up.
- Building confidence: Repeating mock tests can help build your confidence by familiarizing you with the exam format and the types of questions that are asked. This can reduce anxiety and improve your performance on the actual exam.

Conclusion:
Both focusing on new mock tests and repeating ones that have already been attempted have their own benefits. It is recommended to strike a balance between the two approaches. By attempting new mock tests, you expose yourself to a wider range of questions and can identify areas of weakness. On the other hand, repeating mock tests helps reinforce concepts, improve time management, and build confidence. Therefore, a combination of both approaches will contribute to a comprehensive and effective exam preparation strategy.
