Would use the simple present tense, since it is still happening : C'est une expérience intéressante jusqu'à maintenant. I guess you could use the "passé composé" too : Ça a été une expérience intéressante jusqu'à maintenant. "Fun expérience" should translate as "expérience plaisante" or something. But we rarely use this. In Québec, we would use the English word "fun" as this : "expérience le fun". You would never hear this in formal French, but it is widely used in day-to-day conversations. Also, as another user pointed, we would say "à date" instead of "jusqu'à maintenant". Hope it helps, Mathieu

As always, you give clear explainations. I very much enjoy reading your articles.

 

Can you tell me if "hui" is used the same way as "jiang", as "will" would be used in English?

 

Thank you,

 

Mathieu
