Of course, Xia Xibei wasn't admitting defeat.
With her powerful memory, she had managed to finish reading all the required books during the past few days after her return.
Her memory was so powerful that it took her just one glance to remember what she had read. Better still, she was able to read ten lines at once.
Besides, she had always been fast when answering questions. She did questions that she knew and questions that she didn't know both at the same speed.
For the ones that she knew, she would come up with the answers rapidly.
For the ones she didn't, she would skip them directly, wasting no time.
Furthermore, she was an arts student, so the majority of knowledge relied upon memorization.
