Iv been offered an interview for a Grade 2 box. My first question is about the school. I'm currently in full time employment and iv seen many people mentioning how hard the school was. I was never good in actual school but seeing other people struggle amd talking about many exams, how likely is it that you can fail? I'd hate to give up my current job then fail the Signaller training then have nothing as I couldn't go back to the job I have
