I had a rough time through school and didn't do any gcse's. I corrected this a year down the line and did an adult literacy & numeracy equivalent (to a c/d) and also took a bunch of computer courses (ECDL, CLAIT, and lots of other random crap.) I want to join the royal signals. Today i took the barb and scored 48, with a level 1 literacy score and level 2 numeracy. I asked to re-take the barb test and they sorted that for me. Basically the job i have my heart set on requires: "You should have: Qualifications: GCSE grade C in English Language, Maths and Science/ICT" This is for Communications Engineer (Signals). Basically did i screw it up in school and lost this opportunity, or if i show huge determination can i somehow redeem myself as trainable in their eyes?
