There are many useful resources available, including several books that our consultants used to pass their own Fast Stream assessments.
A few years ago the specific Verbal Reasoning and Numerical Analysis test stage was omitted. The numerical analysis has been built more into the initial stages, as part of the SJTs and WBSs, and also more analysis is placed on the Policy Written Exercise, now the Analysis Exercise.
We HIGHLY RECOMMEND candidates prepare for the early assessment stages and the FSAC Analysis Exercise using these books.
The verbal reasoning books may also prove helpful for when you need to quickly draft in the FSAC Analysis Exercise.
