Hi Manshi,

Yes, you are able to give improvement exams in three of the subjects (Maths, English, and Hindi) in the year 2025 as long as you appeared for the Class 10 CBSE board examination in the same year. CBSE enables the collective group of students improving in one or more subjects in the same calendar year through the Improvement Exam or Compartment exams that are usually held in July (following result announcement). Since you are dissatisfied with your 78%, and you can improve in each of the individual subjects, that means you are eligible to apply for improvement examination. Just ensure you apply within the deadline when the registration will open on the official CBSE site. As an additional note, improvement exams are only allowed in subjects that you already passed (you must have already achieved the minimum grade).

Keep checking the CBSE (https://www.cbse.gov.in/) website for updates.
