As biology unit 3 issue report. help me please~~

Hi, currently I am doing the issue report for As biology unit3, the topic I chose is sleeping sickness and I've already done lots of research on it. But just now I found that nobody did this topic from the examiner's reports so I am a little panic...Anyone can give me some suggestions about this topic? Whether I should continue? Although I haven't met any 'fatal' problem while doing the research for this topic...thanks a lot
By the way, I'd like to hear any advise about what I should take care when I start to write the report :smile:
