Completely Comprehensive & Essential

If you want to become knowledgeable and proficient in English Grammar, this seems to be the tool for me.
I’ve always gravitated toward a greater understanding of the English language and all of its components. This app is packed with everything that I need, including the interactive quizzes that await me at the end of each segment.
I’ve finished school with complimentary academia along with some college level training. And I must say that my thirst for learning new things about the English language never ceases. This Learning app is what I need to quench my appetite for the many facets of English Grammar!
Thank you (Teachers and Developers) for compiling all of this information in one virtual book, so that I can use it on-the-go!!!

I have always struggled with grammar. Now there is finally an app that I can use as study material or just to use as a reference. Fantastic!

Eh, I like it but one problem, maybe multiple

The quizzes are soulless and repetitive and should give me different questions and answer choices so im not just mindlessly picking an answer without trying to think. I like the reading part but that doesn't matter when the quizzes are literally the same every time. Also multiple choice question arent good anyway...try implementing more written responses, that way reading the info can be easier to remember.
