Hi.
Firstly, I listen speeches, podcasts 1 hour in that language everyday. Totally, 40-50 hour.
After this, I read texts aloud for a few days, maybe one week or 10 days.
Pay attention here, after this I begin to learn Grammar and vocabulary. Necessary Grammar knowledges, necessary vocabulary.
After learning somethings, I begin to practice. For example, to write a diary, to conversation. Thnx for reading :D
