Here you can find a model test for Norwegian. It consists of 4 parts: Reading comprehension, listening comprehension, writing and speaking. You can download the written parts and listen to the audio files.
Even if you want to be tested in another language (Danish, Icelandic, Finnish), the model test will enable you to get to know and better assess the individual parts of the test. (Swedish is tested via the SWEDEX exam; there is also a model exam there).
