Dear student,

After the corona hit India, the schools and colleges address closed since March. And now, the central government is giving the pressure to open the colleges and schools. But this decision of opening the schools and colleges completely lies in the hands of state government.
So, the studies and most of the exams of schools and colleges are taken online. And also in delhi there aata nearly 800 cases every day and 5 new corona variant cases have also been found.

So, according to me the pre boards can be taken online. Because this exam is not conducted by cbse (generally). So, you must contact the school teachers regarding the mode of exam.
