how can i learn as much french as possible in 4 weeks? has anyone a good side or idea how to do this?
Buy a good self study book, that's how I've been learning Russian (Well, to be fair I also live in Russia, so it's all around me) and it helped me a lot in a very short time frame.
Also +1 to french movies with subtitles and marking things around the house with stickies in french. The vocabulary is the easy part however, french grammatics are a PAIN in the ass, and for that you'll either need a good book/program and/or a teacher. Also, put your phone and computer in french, basically submerge yourself in the french language as much as possible.
