Hello Ankit.

Yes you have to give practical in your board exams of 2020 along with theory exam also.

If you are a regular scholar then no need to worry your college will arrange the things at your own college.

If you are a private student then CBSE will make a centre in your city for your practicals. You will get the information in notifications.

Hello dear aspirant

It is not exactly your headache actually your college will be looking into the Matter. Most probably these will be at your own college for regular students. And in case you are a private student then CBSE will make a centre for the same in your city itself.

Ok good luck
