“To catch up” también se dice en EEUU y me imagino en G.B. también. En este contexto significa “ponerse al día”, es decir, cuando dos amigos se cuentan sus últimas noticias.

I’m very keen on reading your audios, I think you had a fantastic idea so thank you so much

I recommend to everybody to write down on a table in MWord for example the most interesting words, expressions, etc so that you can take a look at them from time to time or before giving a composition to your English teacher as I usually do. It will be a huge data base which will help you to improve.
