Introduction:
Yes, there have been some changes in the CBSE (Central Board of Secondary Education) Class 10 examination pattern. These changes were implemented to provide a more holistic and comprehensive assessment of students' knowledge and skills. Let's explore these changes in detail.

1. Introduction of Internal Assessment:
Previously, the Class 10 board examinations were conducted solely based on the performance in the final written exams. However, now there is an inclusion of internal assessment in various subjects. This internal assessment component carries a certain weightage in the overall evaluation.

2. Weightage of Internal Assessment:
The internal assessment component carries a weightage of 20% in the overall evaluation of subjects like Science, Social Science, and Mathematics. This means that students' performance in internal assessments will also be taken into consideration while calculating their final marks.

3. Internal Assessment Components:
The internal assessment can include various components such as practical work, projects, assignments, and activities. For example, in Science, students may be assessed based on their performance in practical experiments and activities conducted throughout the academic year.

4. Practical Examinations:
Apart from internal assessment, practical examinations have also been introduced for certain subjects like Science and Social Science. These practical exams are conducted at the school level and carry a separate weightage in the overall evaluation.

5. Changes in the Question Paper Pattern:
The question paper pattern has also been modified to assess students' critical thinking, reasoning, and analytical skills. The new pattern includes more application-based questions rather than just theoretical knowledge. It aims to test students' understanding and their ability to apply concepts to real-life situations.

6. Focus on Internal Choice:
The new examination pattern also provides more internal choice to students within the question paper. This allows students to choose questions from different sections according to their strengths and preferences. It provides flexibility and encourages students to showcase their knowledge effectively.

Conclusion:
The changes in the CBSE Class 10 examination pattern, including the introduction of internal assessment, practical examinations, and modifications in the question paper pattern, aim to provide a more comprehensive evaluation of students' skills and knowledge. These changes encourage students to develop a deeper understanding of the subjects and enhance their critical thinking abilities.
