I'm a native French speaker, moved to Singapore 2 years ago.
You would be surprised that French language can be easy to learn. I'd be happy to teach it to anyone interested (grammar, spelling, vocabulary, pronunciation, discussions...). I have some experiences working with kids in a summer camp and teaching students to support them in their exams preparation.
FYI, many countries have French among their official languages such as Canada, Belgium, Switzerland, France, Luxembourg and 10+ African countries.
Feel free to drop me a message if you have any question :)
To learn French, it's recommended to listen French conversations, try to speak it as much as possible and do french exercises.
It depends on the level you want to reach and how many French courses you can do per week/month. In a few months, you will be able to understand simple conversation and to react on some topic/subjects.
