Not allowed to write Mains exams

Dear Editor,
I would like to convey my personal grievances to APPSC.
On Nov 10th, I had gone to kingcup public school for the APPSCCE mains examination 2018 but when I reached there, I found some fellow aspirants shouting slogans against the commission.
Despite the protest, I had made my mind to write the exam but when I tried to enter they stopped me so I waited for adequate space to enter the examination hall. But protest became more intense and we were left outside.
Later when the protest ended, I thought we will be allowed to write the exam but to my utter surprise we were declared invalid. This is totally unfair.
Therefore, I would like to request the commission to kindly find some alternative.
