Recently, we had done quite a number of group work. Five members altogether. Also we had presented many of our case studies and also assignments, including metal alloy case study, principle tech case study, business plan, nano and supposedly halaqah. Just now, we'd completed our case study presentation for principle of chemistry technology, which I found to be such a havoc. I think I didn't give it all for the presentation. I was somewhat slurred while presenting my part.
