Answer

It would be more common to say, " business is booming". 
You could use the word "flourishing" which also means "active" and "prosperous".

My business is booming. The students are happy with my classes. Their tests results are very good. 
They are getting excellent grades.

Hope this helps

In English, we always put at least one space after a period and we begin sentences with capital letters.
