In the Lap of Luxury novel (Grace and Benjamin) novel Chapter 484

Xander looked up and met Victor's eyes without trying to hide anything.

"Didn't she say that she was going to come over with the two of you?"

Victor explained, "Her grades have dropped recently, so Grandpa arranged some tuition classes for her. That's why she can't come at the moment."

"Oh, what kind of classes?"

"Mathematical olympiad classes."

Xander remained silent.

…

The next day, Grace arrived at her mathematical olympiad class disinterestedly. "This is so hard. Can I just not come?"

She had just finished speaking when she looked up to see Xander sitting in her seat. Grace rubbed her eyes and went up to him in disbelief. She asked, "Xander, what are you doing here?"

Xander didn't even look up as he said, "I heard that you can get extra credit if you do the mathematical olympiad, so Mom signed up for me."

Grace was amused at his plight. "I thought I was the only one who was suffering, but I didn't expect Aunt Hestia to do the same to you!"

"Yep, we're in the same boat."

"It's just that this math olympiad thing is really hard!"

Grace wanted to cry. When could she stop learning this?

Xander smiled in resignation, took her textbook, and flipped it open. "I don't have any problems with the questions at your level. Shall I teach you?"

"I just looked at the question you were doing. You're already going about this the wrong way. You see, from the question here, you can tell that …"

Grace had only half-understood it before, but after listening to Xander's explanation, she finally got it. "Xander, I understood it at once when you explained. Why can't I understand anything when the teacher is speaking?

"I think you explain it so much better than the teacher! Can you teach me the questions I can't do in the future?"

Grace looked hopefully at him, like an adorable little kitten.
