Hi there!
I have just discovered the "Telegram" app and this is great!
This app allows you to send text messages or voice messages for free! This is amazing! You can use it with your classmates but also with me and practice whenever you want! My username is @LJ_englishcpge
It would be great if you could send me voice messages from time to time, even if it's 20 seconds long (or just 1 sec long with one word)! The more, the better!
Practice makes perfect!
You can download it here for free!
Here is an interesting link dealing with the pros of using Telegram (British Council).
