English Grammar in Use (Supplementary Exercises) isn’t the sort of book that one reviews, so I will keep this brief.
Freshly updated for 2019, this book complements the new fifth edition of “English Grammar in Use” by providing additional practice exercises for students to work through. And exercises are all you get here – there aren’t any explanations provided.
The exercises are fine. They seem to be more contextualized than in the main book, which means they are more likely to take the form of emails, dialogs and articles. That’s a great choice for a supplementary book that digs deeper than a primary classroom textbook.
The exercises in the book are match the units in the main book, but since this is a shorter book it combines units. Note that these aren’t always sequential (it starts with five pages of exercises about units 1-4 and 19 and 25), but the groupings are logical and obvious.
Overall, I do recommend this book to intermediate level students and teachers… just as long as you already have the main book.
I should also mention that unlike the main book, this one is in black and white and is printed on non-glossy paper. That means it is much cheaper.
Finally, I haven’t seen the fourth edition of the book, so I don’t know exactly how much it has been updated. Anyways, that edition seems to be selling for even more than this one, so I guess you don’t need to bother with it.
