Edit 1: The test asks **not to pick words you are seeing for the first time, only the ones you already knew before the test**. That is specially true for the katakana words.
Edit 2: According to u/fujirin, the **test is aimed at native japanese speakers**.
>I’m a native Japanese speaker and took the test (Reiwa edition) honestly. My result indicates that my vocabulary consists of 71,872 words. This test is designed for native Japanese speakers, and even junior high school students know many more words than those required for the JLPT N1.
