11. Creating a Revision Timetable | 制定复习计划
A wealth of resources only works if used consistently. Start by mapping out the OCR specification topics across the months until your mock and final exams. Assign specific resources to each topic – for example, Monday: Seneca 'Network topologies', Wednesday: Craig'n'Dave video + Isaac questions, Friday: past paper section.
丰富的资源只有在持续使用时才能发挥作用。首先，从现在到模拟考和最终考试，按月规划 OCR 大纲主题。为每个主题分配具体资源——例如，周一：Seneca“网络拓扑”；周三：Craig'n'Dave 视频 + Isaac 练习；周五：真题部分练习。
Build in 'buffer' weeks for revisiting challenging topics and include short, sharp retrieval sessions at the start of each study block. The Pomodoro technique (25 minutes focused study, 5‑minute break) works particularly well for coding tasks and concept reviews.
安排“缓冲”周以回顾困难主题，并在每次学习模块开始时加入简短、高强度的提取练习。番茄工作法（25 分钟专注学习，5 分钟休息）尤其适用于编程任务和概念复习。
12. Discussion Forums & Peer Study | 论坛与同伴学习
Explaining a concept to someone else is one of the deepest forms of learning. Join The Student Room's OCR Computer Science forum or subject‑specific Discord servers to ask questions, share revision notes and clarify misunderstandings. Often, peers can explain a tricky topic – such as the fetch‑execute cycle – in fresh, relatable language.
向他人解释概念是最深层次的学习形式之一。加入 The Student Room 的 OCR 计算机科学论坛或学科主题的 Discord 服务器，提问、分享复习笔记并澄清误解。同伴往往能用新颖、易懂的语言讲解诸如“取指—执行周期”这样棘手的主题。
Form a study group of two to four classmates and meet weekly to tackle a past paper question or review a programming algorithm together. Set ground rules to stay on task and use the session to teach each other one topic. This collaborative approach not only boosts motivation but also exposes you to different ways of thinking.
组建一个两到四人的学习小组，每周聚在一起讨论真题或一起审核编程算法。制定规则确保集中注意力，并利用聚会互相教授一个主题。这种协作方式不仅能提升动力，还能让你接触到不同的思维角度。
