Hi Rakia, 

Please remember that in English we only need to use one question mark(?) or exclamation mark (!)

Would it work?

I'm studying Cooking write right now and I want to let the whole world know about Tunisian food and sweets. 

One day I want to have a pastry shop one day in Korea and I'm wondering if these kind types of sweets can could work in Korea?

Could someone please help me?

These sweets are made only with nuts and suger, and nothing else.
