You can translate a test to another language by changing Chosen language, but it is probably easier to use The translation tool. Here I have created a normal multiple choice test on Norwegian Bokmål. To translate it, I click on Translation tool.
The first thing we have to do is choose the language the test is being translated to. You choose the language from the pull-down menu.
Here I have chosen to translate to Norwegian. On the left side, you can see the text that is put in as English and in the box to the right, you can write the translation.
If the text is the same as the original, you can click on copy. You can also do this if you have pictures you want to use in several languages.
When you are done, you click Save translation and choose Test editor to go back to the editor.
