English Grammar Workbook - Betty Schrampfer Azar
I still remember how worst my English was before I came to know these workbooks. Even though I don’t have excellent English now but at least I can write and speak.
These 3 books did help me a lot in English Grammar. These 3 books made me love English language. The author explains English grammar in easy to understand English. The most important thing is there are a lot of exercises in these 3 books make you truly understand what you have learnt from the notes.
For those who want to learn English from basic, I recommend the 3 books above. 
Red – Basic Level
Blue – Intermediate Level
Black – Advanced Level
