andrew,
from the faststream website:
"Being successful at this event is determined entirely by the email multiple choice responses which generate an overall score. The scores from the Verbal and Numerical Retests are to establish a score under “invigilated” conditions and are only used to compare with your previous test scores. If, having been successful in the e-Tray multiple choice section, the retest results vary by a substantial margin from your earlier scores (i.e. are considerably lower), the Cabinet Office will review your application and this may result in your elimination from the competition. The written response is only assessed if you are successful at e-Tray and forms part of the Fast Stream Assessment Centre (FSAC) process"
The written test consisted of 2 equal sections:
1 a written ministerial briefing summarising the rational for the introduction of the proposed government scheme which you have been researching in part 1 of the e-tray exercise.
2 a blue skies thinking exercise where you were encouraged to develop as many creative ideas as possible in order to address an area of the proposed scheme that had given cause for concern
Hope this helps, when have you got yours?
Good luck
