Key points for students
The schedule released by CBSE is tentative, so students are advised to regularly check the official website for any updates or changes. Since practical exams are conducted separately, it is important for students to confirm the exact dates with their respective schools to avoid any last-minute confusion.
For effective preparation, students should align their revision with the date sheet, begin by strengthening weaker subjects, and make use of previous years’ question papers to get familiar with the exam pattern and question types.
