When tutoring 2391, it is part of my role to encourage candidates to use 7671 and GN3 as much as possible. Those are the only printed documents permitted in the online exam. During practical training, the lads are encouraged to collaborate with each other and use said documents to check test results and design data. I note many just defer to their smart phone to access even rather obtuse data buried in the bowels of 7671.
As much as an old timer like me likes his books, I think it is time that we acknowledge that smart phones will be the primary data source for most operatives. The exam bodies would do better to address the application of data rather than the simple ability to access it.
