what do u suggest? pls give all information. thks

Just 4 weeks, I'm not suggest you to find a language school, it will cost you too much and there aren't any great improvements.
Make some chinese friends, stay with them, listening more, speaking more. It's difficult to expect quick results, Keep practicing with chinese every day.

Suggest you ask help for foreigners, some of them have more experiences learning Chinese :)

Hi!! I'd like to know if anyone got any info about chinese classes during summer!
Thanks!

@mooonlight, there are many schools offering summer courses (e.g. Keats and Mei's Mandarin).

Alternatively, you can get a private tutor which might cater for your needs more flexibly.

@kurtosis
Thanks a lot for your reply!! I will check those schools! The private tutor would be useful but having classes is even an way to meet some people!
