This is invaluable: it's all there. To get back, to review, this is the book for you. Very well done with the clear lesson with examples that facilitate learning and exercises relating to it, not to mention corrected to see if really the point of grammar is understood and acquired. This is REALLY a great book to learn, revise or remember English grammar. I recommend it to all who like me, after putting the English side for many years, want to do it again.
