Which grammar book do you recommend?
We do not recommend any grammar books because they are not going to help you practice effectively or give you feedback on your performance. This is what you actually need, not a reference book.
Grammar exercises can help you realise if you need to improve a certain area of grammar, but spending hours doing fill-in-the-blanks exercises will not help you avoid mistakes when you write an essay.
If you are struggling with grammar, it's might be because you don't know the grammar rules, or it might be because you don't know how to apply them. Just because you can list off the rules for articles does not mean you can write an essay without articles mistakes.
The Challenges & Skills can help you apply grammar rules and avoid making mistakes.
