well i dont think so, if you want to speak a language fluently, the most important thing is not what you learn how the book, almost it is also important, the most crucial thing is to speak to native speakers or go to the country, cuz theres no way you can learn the way they speak just by repeating what you saw in the book. i thought that i speak english really well until i went to high school in the US for the first year, no matter how perfect my grammar was, people could barely understand me because of my accent and i could barely understand them because of their slang and their way of speaking. well of course thats just my point of view, i hope that helps!!
