Final answer:
To write a report about your school's performance in the interzonal competition, provide background information, highlight specific accomplishments, and include supporting evidence.
Step-by-step explanation:
Writing a report to your headmaster about how your school performed well in the interzonal competition is an opportunity to highlight the achievements and successes of the school. Start the report by providing some background information about the competition and the participating schools.
Then, focus on your school's performance by highlighting specific accomplishments, such as winning medals or awards, achieving high scores, or demonstrating exceptional teamwork. Include supporting evidence, such as photographs or statistics, to substantiate your claims.
Make sure to use correct spelling and grammar, and write in complete sentences. Keep the report an appropriate length, neither too short nor too long. Conclude the report by expressing gratitude to the headmaster for their support and mentioning the pride and motivation the school feels due to the successful performance. Finally, proofread the report and revise any errors before submitting it.
