I applied for revaluation once already as I only need one mark for A* and the question below looks like it has a chance. However, when i got my results not only there wasn't a single change in my marks but even the correction looked identical. My answer clearly say gibbs is negetive just like the marking scheme but I haven't received even one mark both the times. Please look at the question and tell me if I'm wrong or scambridge is finding new ways to make money.
