This question already has an answer here:
Now I don't know anything about German but I want to learn German up to level C1. I plan to learn German alone as much as possible. So I'm looking for books to help me reach my goal. I intend to first learn about IPA (International Phonetic Alphabet) and phonetics. I found an excellent material about phonetic in the book "The German Language - A Linguistic Introduction" written by Jean Boase-Beier and Ken Lodge. I also found some sites that complement this material. After I learn about this I plan to read the book "Hammer's German Grammar and Usage". However I don't know what material I should learn after this book.
Researching I have seen that the Cornelsen books are excellent however they are not digitally available (I can't access the books through the Kindle, for example) and they come with CD's. I don't have any CD players.
Could you give me a collection of books (and tell me in which order I should read them) that will allow me to reach the desired level?
I intend to study this way because I believe that this is the most systematic way to learn German. I'm not interested in conversation right now, but at the right time I'll look for a teacher to practice conversation. My initial goal is to be able to read Mathematics, Physics, Biology and Chemistry books in German as fast as possible.
