I want to give improvement exam 2021 for hsc so tell me that the portion will be changed or will be same as it was in 2020
As per I know there are no search official notice regarding the changing of syllabus for 2020-21 season. So if you want to give your improvement exam in 2021 for HSC, the portion will be same.
You also should check your board official website.
Hope this will help you.
