Can anyone help me? I am currently going through the re-enlistment process with a view to joining this Corps, however I have been told I will have to take a Technical Selection Test. Can anyone shed any light on to what this entails? I have been told it is similar to a GCSE maths exam but I havn't done any sums in 10+ years and am very rusty in this subject. Any pointers to on-line revision aids would be greatly appreciated.
