Tomoko's study habits
Not particularly important to the story, but how often do we see Tomoko actually studying? Way back in Chapter 44, we found her in the coffee shop trying to study, because of the threat of being sent to another school, but we mostly saw her fail to study because she was distracted by the anime running on another patron's laptop.
However, we know she eventually succeeded, because she improved her grades enough to stay put.
More recently, in Chapter 90, her homeroom teacher reported to her mother that Tomoko is "diligent and takes school seriously." We know she has some standards when it comes to schoolwork, because she often thinks of academic success as one path to impress her peers, and she was immensely scandalized when she found Yuu-chan so cavalier about the F's on her report card way back in middle school. From Chapter 16 of TomoMote: "I knew she was retarded, but I didn't think she was
that retarded!" In Chapter 68 of WataMote, we find her achieving a perfect score on a test after applying her active imagination to a subject of study. She does have an active and engaged mind, for all her laziness and time-wasting.
