I used the DVLA book for the module with questions but did jack with regards to hazard perception. It wasn’t anywhere near as the same as the clips you get on the net. It was basically 1 hazard in a video and the potential for two hazards in 1 video out of the 20 I did and I passed. It is very similar to what you would normally do (but do automatically) when driving. A car pulling up towards a left side junction too quickly, a passerby about to cross a road, a chap in amn electric wheel chair crossing a junction and a car turning in, that sort of thing.
