Adobe InDesign CS4 Exam

I am a college teacher, it's clear to me that 2 month ago, one of my students came to ask me whether it's a wise choice to get a IT certification, which made me think of my 26 years old daughter, who is still an assistant to a department manager.
I suggested her to take the Adobe 9A0-086 exam with the words my student said to me. After a long time talking, she agreed, do you know how happy I was! About 2 days later, my student decided to attend a training class, so I made up my mind to prepare all the things for my daughter. But when I came to tell her that she should to attend the class at night to study the materials, she argued with me! A surprise turned out to be a suffering for me!
I have recognized my mistakes, but I don't know how to change the relationships between my daughter and me! Can anyone help me? 9A0-086 Adobe InDesign CS4 Exam
