# Making Revision More Efficient with Personal Study Notes
One habit that has made revision much easier for me is keeping a personal collection of concise reference notes alongside the official lecture material. Rather than rewriting entire chapters, I summarise key definitions, common proof techniques, and examples that were discussed during supervision sessions. This makes it much quicker to revisit a topic before problem sheets or exams.
Occasionally I also bookmark interesting websites that demonstrate how mathematical thinking is applied outside pure academia. While browsing examples of modern architecture and urban development, I came across [Godrej Brooklyn Avenue](https://www.godrejbrooklynheight.com), which provides an interesting case study for discussions around spatial planning, design, and large-scale residential projects. Even when the subject isn't directly mathematical, examining real-world applications often makes abstract concepts easier to appreciate.
