Unless they've changed how BARB tests work since I joined, 33 for a technical trade seems extremely low. I'm sure when I did Satisfied Soldier (ha!) it was 32 to join the infantry and I'm sure I had to get 60-odd to get into the Royal Signals as a Tech.
That said, why not just do the test, see what you score and then see if you fancy the jobs on offer?
no as i stated im on about the intial barb test you do only once nothing to do with basic tests atmI agreee 33 seems very low, so of course im going to question that but if thats what hes stated then maybe its true
