I thought this subject was the easier one out of the two genetics subjects. It is mostly ROTE memory so if you understand the content and can memorize it then you will do good. Some of the content crosses over with MCB from biomed 2nd year and also BCMB20003 (mainly the cyclin stuff and transcription etc) so if you've done either then you will be on familiar ground.
The MST I enjoyed. I found it straightforward. I believe it was predominantly multiple choice true/false. A lot of people complained that the MST was too focused on nuances with subtle wordings and double negatives rather than a true demonstration of your knowledge (which short answers would be better for). I think if you know your stuff you should do good on it but I can see how reading comprehension would come into play.
The assignments are both interesting. You get a science article and a list of questions. You have to read the article and answer the questions. There's a deadline and you can do the questions anytime before the deadline and submit it whenever you want (no time limit). Working in a group makes this easier. They're designed to teach you how to reach scientific articles etc. The articles aren't just random pieces though. They are relevant to the lecture material so if you know the lecture material then the articles will make more sense.
The exam I think was pretty good too. Basically standard multiple choice, short answers, etc. If you know your stuff then you should do well. There isn't really any trickery. Questions for both the exam and MST are recycled so definitely do them.
