Student can control the formality level of their writing — choosing the right register for the audience and context.
Introduction to tone, register, and academic voice
You already know how to code-switch. The way you text your best friend is completely different from the way you write an email to your school principal. This shift in language based on your audience is called register.
In CBSE Class 10, moving from a "good" answer to a "topper's" answer means mastering the shift from basic academic English to a sophisticated, higher-order register.

Practice upgrading informal sentences to academic register
When writing answers for your CBSE board exams, it is crucial to avoid language, such as everyday slang, and adopt a formal academic tone. For example, instead of saying a new factory 'totally wrecked' the local environment, you should state that the development degraded the ecosystem. Rather than describing a freedom fighter as someone who was just 'good at talking,' you can upgrade your register by calling them an and inspiring orator. If you want to express that a leader 'spoke clearly' about their plans, you should write that they were able to their vision effectively. Finally, instead of saying you will 'look at' the data in a science experiment, the academic register requires you to the given information.
