My Son's Exam Story 2

My family and I ate had dinner at a good place with my family last yesterday. Because My son said claimed that he did well on the exam, but as I still do not see his grade result.
On the positive side, aspect, he tried to talk discussed the about exam with me. But there is a limitation in case of his good result. ??? I don't understand this and unable to guess your meaning.

Regardless of Whatever his grades may be, result, I hope that my son can feel freely to discuss things with me, tell me about his whole things include exams or otherwise.

For providing this condition, By showing me that he can discuss, this is all I can do. What I have to do? I am only guessing.  I don't understand your intent.
