Welcome to NetLearn Languages-the home of live, online language learning!
Let us help you improve your language skills! With us you can study English, French, Spanish, Italian,
German, Russian and other languages live via the Internet with qualified and experienced native-speaker
teachers using the free Internet conferencing program. In your lessons you will practice speaking the
language you are studying with your teacher, work on exercises and work-related files together, and more.
Private Online Lessons
If you need to improve your language skills quickly and would like the full attention of your teacher,
private lessons are for you. With us you can study one-to-one with a teacher, meaning that all lessons are
prepared specially for you. We also offer small groups (maximum 6 participants) for you and your colleagues-
you choose exactly with whom you want to study. Private lessons are ideal if you specially need to learn
the language for Medicine, Law or Business.
The Cer@net package
If you need to make a maximum amount of progress in a minimum amount of time, our Cer@net package
will be of interest to you. Offered in conjunction (连同) with our partners, Ceran Lingua International, the
Cer@net package includes 30 hours of live, online language study with NetLearn Languages and a one-week
intensive residential course at one of Ceran Lingua's centers around the world.
