So I have one month until I have to sit an assessment to prove I am capable to do my role (legal requirement). I have been with the company for over ten years, same department, similar role. I KNOW the stuff I'm going to be asked about (regulations, key issues, how I look after team, personal development etc) but I had a warm up practice with my manager today and I just blurted stuff out. Nothing I said was factually wrong but I couldn't articulate or elaborate on anything. I need to be able to speak confidently asap and be able to THINK when I'm speaking (I couldn't even remember what I'd said when it was over!) Please please help. What can I do? I've read everything I need to it just doesn't come out of my mouth like I know anything but bullet points
