In TOEIC there are expected to be words which are relatively relevant to office or business scene, for example, "brochure," "list price," "reimburse," etc.

So I may be recommended to google "ビジネス 英単語" or "オフィス 英単語" etc. and check them before I take a TOEIC.

In an English exam, it may turn crucial whether you encounter a word the meaning of which you don't know or cannot guess.
