A It’s a great buzz; I like knowing stuff and then being able to pass it on to the audience. I really enjoyed that on radio and at Newsround I really like making stuff enjoyable and understandable for kids.

В I only liked English and Art, that was it. I hated everything else — I really did. History, Geography, sciences — I hated them all. But I loved English.

С I did hospital radio and I spent a lot of time going to see bands. I was heavily into music.

D I was trying to get into radio so I didn’t write a lot. I got my experience in hospital radio and then got work experience at the local BBC station and the local commercial station. That’s where I started writing for news bulletins.

E When I was about ten, I’m not sure why but mainly I was really into radio and loved listening to it. I wanted to be one of the news broadcasters and I found out that to get into radio news you had to be a journalist. My dad wanted me to be a lawyer.

F I worked as a broadcast journalist on Red Rose Radio in Lancashire. I was doing some journalist work during the course. The editor I worked for told me that the editor of Red Rose was looking for a journalist, so it was an example of how important networking is.

G I have been a researcher on the Guinness Book of Records and I also worked at BBC local radio stations and commercial stations. I worked as a correspondent for a news service that puts bulletins on mobile phones. Now I work for the Newsround website.

H The worst bit about this work is the hours. It is shift work (работа no сменам): and I don’t think it will ever change.

I You have to be very keen and very confident because of all the competition. Get as much experience as you can by working in the areas that you are interested in. If you are not going to go to college then you have to get a lot of experience. It’s harder to work your way up but I know a lot of people who have done it. It’s another route.
