The novel explains this in more detail.

Spoiler for additional details:

Cecily and Aria had been waking up in the early morning and meeting up twice a day, before and after work, to plan their strategies and techniques in case they had to take on Doris, Margot and Penelope again.

They did this every day starting from their first loss to the trio, until the rematch eventually occurred.
