My friend Ayşe has a very organized study routine. Every evening, after dinner, she spends two hours reviewing her notes and completing her homework. She always makes a to-do list for the next day, which helps her stay on track. On weekends, she usually meets with her study group to prepare for tests. This habit has helped her achieve excellent grades. What is one of Ayşe's key study habits?
A) She studies only on weekends.
