Learn pronunciation first, and the level of pronunciation should be as good as reading when watching, just like learning music and singing when watching music. This is the foundation. The latter is easy to handle. Because what you want is speed, it is recommended not to read books, listen more, listen to the radio and listen to the initial tapes. The best thing to learn is phrases. Don't recite words in isolation. Communicate first. Then get in touch with people who speak French. Two months later, with perceptual knowledge, you can start reading grammar books, understand the grammatical phenomena in the French you speak, memorize words to expand your vocabulary, and thus draw inferences from others. Peiwen pedagogy is very good, and I also studied there.

Good luck with your study!

Generally speaking, unless you have a special language talent, it is impossible to learn a foreign language quickly.

Many so-called crash courses are just for exams.

If you really want to learn a foreign language well, you should listen to the original listening materials, news songs and so on.

You can often go to the original movies without translating subtitles.

In peacetime, we should also insist on reading articles and newspapers written in which foreign language.

If possible, frequent communication with native speakers of this foreign language can improve their oral English quickly.
