The Frank sisters each hoped to return to school as soon as they were able, and continued with their studies while in hiding. Margot took a shorthand course by correspondence in Bep Voskuijl's name and received high marks. Most of Anne's time was spent reading and studying, and she regularly wrote and edited (after March 1944) her diary entries. In addition to providing a narrative of events as they occurred, she wrote about her feelings, beliefs, dreams and ambitions, subjects she felt she could not discuss with anyone. As her confidence in her writing grew, and as she began to mature, she wrote of more abstract subjects such as her belief in God, and how she defined human nature.
