I am often asked to recommend the best basic English grammar exercises online. In book form, the Murphy books have been market leaders for over 25 years. But some Internet grammar exercise sites have been going for almost 20 years with great success. I’m proud to say that my English Grammar Secrets site is celebrating 15 years of success and is still among the top-rated on Google for English Grammar Lessons. I hope you’ll pay it a visit if you have a need. I’m working on brand new basic English grammar exercises all the time.
