Shin Kanzen Master Essential 2200 Words for the Japanese Language Proficiency Test (JLPT) N2

Shin Kanzen Master N2 Wordbook covers 2,200 words organised by topic: economics, medical, disasters, international politics, arts, IT, and more. Every word comes with an example sentence showing how it's used, and every 200 words a reading passage lets you see them in real context. Related compound words and derived words are grouped together so you pick up word families, not just individual items. The book also covers prefixes, suffixes, and counters. A free companion app provides audio for all the words and reading passages. Comes with English, Chinese, and Vietnamese translations and a red overlay sheet for self-testing.

Shin Kanzen Master was designed to build learning into each book alongside the test prep. Vocabulary is harder to do that with, and the Wordbook sub-series seems to be 3A's answer: split it into two books, one for learning and one for testing. This is the learning side. The format is more than a word list. You learn a word, see how it's used in a sentence, then meet it again in a reading passage. If you're using the Vocabulary (語彙) drill book, this pairs with it. It also works on its own if you prefer working through words on a page over flashcard apps like Anki.
N2 vocabulary is abstract, formal, and topic-specific, and you won't pick most of it up from everyday reading alone. This gives you a structured way to work through it.
