Ways to avoid malpractices in board exams

There are two ways to avoid malpractices in board examinations. One is that We can install CCTV cameras in board examination centers to avoid copying, using bits. Cameras should be installed in center of the hall in the ceiling, so that camera gets full view. There should be a common control room in every district to monitor it. We should keep the footage for one year, in case we need to cross check any complaints we receive. Another way is for avoiding management to give bits to students. Instead of allocating one hall for a single school, we can club at least 4 school students from the same locality in a single hall. Every four consecutive seats, there should be four different school students. So, if management wants to give bits, it has to give bits to 16 halls instead of 4 halls, if the school's strength covers 4 halls. Also it will not be a secret, news will spread.
