whats the need for protest now?

There's no point in doing protests now. They've reduced the revaluation fee already. If you think you revaluation will increase your marks then go for it ! and to anyone who is worried that they'll not increase your marks in fear of 'losing their reputation' , thats not happening. You'll get the pdf of your answer sheet, match the answers with marking scheme (which will be available soon) and if your answers are correct then they'll definitely increase your marks, otherwise you can file a lawsuit against them.
