hi so im im year 11 and my gcses start next week. I asked today (I know its late) about leaving like I have a timeout card in lessons when im really anxious and my PSO said that if you leave you can't go back in. Is this true? What happens if you were to have a panic/anxiety attack in the exam? I have undiagnosed anxiety and get a smaller hall but im so anxious. any help would be much appreciated
