CBSE syllabus and sample papers are tools of learning during various practice and revision sessions. Practice is an important technique of learning for CBSE examination. Model sample papers framed within the CBSE syllabus of Class VII to Class XII help students to use them as resources of practice. Practice marks the performance during the examination. If you practice regularly then you have developed higher level of confidence. Some prefer to prepare notes and to revise their notes repeatedly. CBSE sample papers can be useful to both to prepare notes and revise and also from the point of view of practicing for the examination.
Preparing notes from CBSE sample paper by answering the questions and revising them is easier than practice. But when a student learns he should learn to prepare for unknown challenges. Practice prepares for challenging learning sessions and leads to them to the path of the discovery as they answer questions without any assistance, as a student can pick up a model paper and attempt a mock examination in a practice session. Whereas, preparing for revision gives notes for practice which is mostly prepared by students with help from text books and other supporting references. Mock tests can build confidence step by step to face examination, better than preparing notes and revision. Even then both revision and practice are important for students.
