Learning Vocabulary (vocabulary is always plural)

Until today So far I have learned over 1000 (one thousand) words. I prefer to learn words with "babbel" because it is (it's) easy, but if others learn with flashcards that is also good.  I like babbel because it remember reminds me to learn vocabulary and (it) is structured in different steps. If I am absolutely finished with a word (then) I don't have to repeat it. But I know (that) you can to the same do that yourself. I learn a lot of words I never will/(will never) need in school but I'm sure (that) they could become important when I'm going in to English speaking countries.

How many words to will(?) you learn (have you learnt?)?

(* If you have written something in German (but not a book :D) write me and I will correct it :) )

P.S. http://www.memrise.com is a really fun way to learn new vocabulary :)
