Hello Rashmi,

The role of practical exams in the overall assessment for the JAC 12th exams includes following :

1. Skill Evaluation : Practical exams assess students' hands-on abilities in subjects like science, arts, and vocational courses.
2. Weightage : They carry a significant weight in the final marks, usually around 30-40% depending on the subject.
3. Understanding Application : They test the application of theoretical knowledge in real-world scenarios.
4. Boosting Marks : High performance in practicals can improve overall scores, especially if theory marks are low.
5. Practical Knowledge : They ensure students understand the concepts deeply beyond memorization.

Hope it helps !
