No, usually you don’t have to give practicals again if you’re appearing for the Class 11 improvement exam. If you had already passed your practical, then those marks are carried forward and only the theory part is repeated.

But incase if you had failed or missed your practicals before, then you might have to do them again. Still, it's better to confirm once with your school or board because rules can vary a bit depending on which board you're from.

You should ask or inquire the authorities about the same and stay aware for any other relevant updates

Hi Boojatha,

No, It does not required to give practicals again for the Class 11 improvement exam (as improvement exams are usually only for theory papers and your previous practical marks are carried forward), but this can vary depending on the school board (like CBSE, state board, etc.) so you should ask your school or the official guidelines from your board.
