Hi is anyone studying the Salters Nuffield Advanced Biology (SNAB) course?

The synoptic pre-released article is on sperm. Just wondering has anyone had a mock on it? It is because it's a new course, it's such a real mystery doing the synoptic. Definately meiosis, spermatogenesis etc will come up. Any advice on it, whether or not you do the SNAB course, would be very much appreciated.

Any guess on the essay question part? I have a feeling a similar question on diets is likely to come up...
