Does He Know to Give Mark?

Today I presented the topic of PDCA Deming Cycle. In this presentation, I had done a lot of changes. In the presentation, I gave extra hand-out, I spoke in funny tone and added body language. This time, my group was so improved!! However, to our surprise, we did not receive what we deserve. Our marks was just the same as the previous presentation's. I was about to ask the lecturer "Do you know how to give marks"?? The other presenters' performances were not so okay. But their marks were just the same as us.

I am not being calculative about the marks and emphasise on winning. I was just little disappointed. I feel like there is no improvement in me after I have done so much presentations. Maybe what I need to do is to keep on improving and believe in me again.
