Its is pure inefficency of NTS to conduct tests smoothly. NTS is not capable to conduct test at such large scale. The fault is also at our own side. What I observed was that everyone in the block wanted the liberty of using mobile, but it was only due to invegilator who restrained them.

If mobile was permitted I also had used and got 90+ marks. My current expected score is around 70-75 marks, which I think is good for Science group.
