As the title suggest, I want to know if this book (which can be found [here](https://www.railstutorial.org/book)) has given anyone success, or if they can simply recommend it for it's quality. I'm more or less a beginner at Ruby, but I aim for becoming a master of both languages. I could use this book for my three-four month programming project at school, which should more or less be suitable for the number of pages.
Also, if you have other suggestions, I'd be glad to here them! I have seen a number of other books and resources, but I have to use something free and easily accessible. I'm afraid video lessons just isn't my thing, because of their length.
