How to choose and prepare a good project file (quick guide)
- Pick a topic you like — you will work on it for days; interest matters.
- Match the subject & curriculum — ensure the topic fits your subject’s syllabus and teacher’s guidelines.
- Plan your time — divide work: research, experimentation (if any), writing, diagrams, proofreading.
- Keep records — dates, sources, data, photos — these strengthen your file.
- Follow the report structure — Title page, certificate, acknowledgement, index, introduction, aim/objectives, theory/background, materials/methods, observations/results, conclusion, bibliography, appendices.
- Presentation matters — neat writing/typing, labeled diagrams, charts, proper referencing.
- Practice the viva — teacher may ask about your method, results, and learning.
