Här ser du vilka kursdatum som är tillgängliga. Klicka på en av datumknapparna för att anmäla dig till ett kurstillfälle. På kursen pratar läraren svenska, medan vårt kursmaterial alltid är författat på engelska.

Missa inte vår samfaktureringsrabatt! Är ni fler personer från samma företag/organisation som går på samma kurs och kurstillfälle, rabatteras tillkommande personer med 25%. Ni kan anmäla er till kursen en och en, men uppger då samma företag, så ordnar vi resten. Samtliga deltagare från samma företag ingår då på samma faktura, den första till fullt pris och resterande till rabatterat pris.
