Leanne 1987 - PHONE HR! It's no good asking on this forum what the email regarding the security questionairre means!
On a positive note, they would only need the security form filled out 100% accuaratly if you were succesful at stage 3!
HR may have forogtten to email you regarding the Stage 3 results, the same happened to me, I got to the 15 working days, called them and got told to call back after the weekend to find out! Called Monday and they had temporarily lost my stage 3 results!!!!!!!!!! But they found them and I had passed.....so fingers crossed for you!
To everyone sitting stage 1 - I feel for you so good luck, we were hit with a couple of stage 1 tests the other day that they are thinking of bringing in, it almost fried my brain although interestingly, most of us completed them in the time allotted. (On top of that we had a written exam 1st thing the next morning!)
