"Moving on, I suppose I should tell you about what's going on in college with me." Joyce continued, "I don't think I have ever done better. With the assurance of the fact that I am going to continue with my career from Adrian, I have never paid more attention in class. Also, I'm scoring quite good."
She then went into the details of what she had scored in the series of tests and revisions that had happened in her classes. In Most of them, she was doing good. The one that she was not good in, she was above average so it was alright.
There was no one in her life at the moment who would tried her for her lack of marks if she started scoring less. However, it would definitely have been her mother if she were still alive. So it all came to her naturally. When she told Bianca about the marks she had scored and the one subject that she was not doing well in, she came up with excuses as well.
