The shift to a CBSE board exam twice a year is the most important change school students and parents have seen in a long time, and it directly shapes how Class 10 and Class 12 candidates must plan their year. The Central Board of Secondary Education has moved Class 10 to a two examination model, giving students a second chance to improve their performance within the same academic session, while the policy and schedule continue to evolve. Understanding the rules clearly is the first step to using this reform to your advantage.

What the twice a year policy actually means

Under the new framework, the Class 10 board examination is held in two sessions during the academic year. The first examination is compulsory for every student. The second examination acts as an improvement opportunity, and the best of the two scores is counted in the final result. This means a student who is unwell, underprepared in a few subjects or simply wants a better score in subjects such as Science, Mathematics, Social Science or Languages gets a genuine second attempt without losing an entire year.

Class 10 and Class 12 in the new system

The two examination model currently applies to Class 10. The Class 12 examination continues to be held once in the main session, so senior secondary students should plan around a single major board window. For Class 10 students, the first session is conducted early in the year, followed by a second session a few weeks later for those who choose to appear. The consolidated mark sheet and passing certificate are issued after the second session result, so the official academic record reflects the better outcome of the two attempts.

Best of two rule and how marks are counted

The headline benefit of the reform is the best of two rule. If a student appears in both sessions, the higher score in each eligible subject is retained. A student who is satisfied after the first examination is not required to appear again. This design reduces the pressure of a single high stakes day and rewards consistent preparation rather than one time performance. It is important to remember that the second session is an improvement examination and not a routine supplementary, so students should still aim to perform well in the first attempt.

How students should plan preparation

The twice a year model rewards steady, year long study rather than last minute cramming. A practical preparation plan looks like this:

• Finish the full syllabus before the first session, treating it as your main attempt.
• Identify two or three subjects where a second attempt could meaningfully raise your score.
• Use the gap between the two sessions for targeted revision, not fresh learning.
• Solve previous year papers and sample papers under timed conditions to build exam temperament.
• Maintain short, well organised revision notes for quick recall before each session.

Quality study material makes a real difference, and many families choose standard reference books and well structured notes from trusted academic resources along with topic wise practice sets from curated school exam books. Students who plan to move from boards toward competitive science streams can also explore early foundation guidance from the best IIT JEE and NEET coaching online, which helps build strong basics in Physics, Chemistry and Mathematics during the school years.

The bigger picture for school students

The move to two board examinations is designed to lower stress and reward genuine learning over a single performance. For students in Class 10 and those planning ahead for the 2027 and 2028 sessions, the smartest response is to build strong fundamentals early, stay consistent through the year and use the second session strategically rather than as a safety net. Treated well, this reform turns the board year into a fairer and more manageable experience.
