This was useful because it gave me ideas for my own presentation. However, the format is bad (having one line come in at a time is irritating and distracting). It also isn't applicable to anyone outside the UK (students at my international school will not relate to the examples given. They should have been more diverse). Also, some of the information isn't even correct (humans swallow 8 spiders a year? That is an old wives tale). I wish I could have previewed this before I bought it, but the idea is nice.
