She had no way of tutoring because she wasn't eloquent enough to teach others, and she didn't have time to look for part-time jobs either, as it would only make her studies more strenuous.
Even at her worst, Yiyi had "space-time cheating" at her disposal. Although she was pursuing a dual major, the additional major was merely for enhancement. With the Computer Department's courses inherently more challenging than those of the Calligraphy Department—and since calligraphy classes didn't pose a difficulty for her—she found her studies relatively easy. The only thing she really lacked was time, as calligraphy lessons meant she had to make up for Computer Department classes, and vice versa. She continued to patch up her schedule this way for the greater part of the semester.
