Liang Yan watched Zhang Yu return to her room, her face twisted with anger.
Even spending money to send Zhang Hao to cram school, it was quite a sum, but whether it was effective or not, she really wasn't sure.
She didn't expect Zhang Hao to get outstanding grades, just to be able to get into a key high school, even if he could just get into any high school would be fine.
But now, she's really worried, as if it's an impossible task.
With her hands clenched into fists, "Why, why is that brat's grades so good while Xiao Hao's aren't."
If she could swap their grades, no matter the cost, she would pay it.
When Zhang Yu returned to her room, she was pleased; as long as either Zhang Dong or Liang Yan or Zhang Hao were in a bad mood, Zhang Yu's mood would soar.
In her room, Zhang Yu picked up a math workbook and started looking through it. She spent some time online and found out that studying math could lead to aerospace research opportunities.
