It is time for tests! Unfortunately, Konata cannot seem to concentrate on studying and instead reverts to slacking off and playing games. She tries to ask Miyuki about good study habits, but in the end she does bad on her tests. Tsukasa got help from her sister and this time got better scores, but Kagami's scores were still higher despite her own scores going down somewhat. Later, Konata and the Hiiragi twins go to a cake café but end up taking too much and must finish it all or pay an extra price.
