Final answer:
A well-planned time-management schedule should include time to review material studied in previous weeks to reinforce learning and support long-term retention.
Step-by-step explanation:
A well-planned time-management schedule should include time to review material studied in previous weeks. This is important because reviewing previously learned information helps reinforce it in your memory and supports long-term retention. By regularly reviewing past material, you can identify any gaps in your understanding and address them before moving on to new topics. For example, you can create a concise outline of the main ideas discussed in class and compare it with the outlines of other students to check your study habits.
