English Grammar in Use (Murphy)
The default intermediate grammar book: one point per two-page spread.
What it actually is
Raymond Murphy's blue book has taught grammar to tens of millions of learners with a simple format — explanation and examples on the left page, exercises on the right — covering everything an intermediate learner needs, with an answer key that makes it genuinely self-study. The fifth edition adds an interactive ebook with audio. Companion volumes exist for elementary (red) and advanced (green) levels, so buy the one that matches you; and it is a practice book, not a course, with nothing on listening, speaking or vocabulary building.
