To write a capstone project in a university, you should follow these steps:

1. Choose a topic: Start by choosing a topic for your capstone project. Your topic should be related to the field of study you are pursuing and should be interesting and relevant. You should also choose a topic that allows you to explore a specific aspect of the subject in depth.
2. Develop a research question: A research question is a specific question that your capstone project will attempt to answer. Your research question should be focused, specific, and manageable. It should also be interesting and relevant to the field of study you are pursuing.
3. Conduct research: Once you have chosen a research question, you should conduct research to gather information about the topic. Use a variety of sources, such as books, articles, and websites, to learn as much as you can about your research question. Take notes on the information you find, and organize your notes by topic or subtopic.
4. Create a thesis: A thesis is a statement that summarizes the main argument or point of your capstone project. To create a thesis, you should think about what you want to say about your research question and how you will support your argument. Your thesis should be clear and concise, and it should capture the essence of your capstone project.
5. Write the capstone project: Once you have a clear thesis, you can start writing your capstone project. Follow the guidelines provided by your university or instructor, and use the research you have conducted to support your argument. Be sure to properly cite the sources you are using and to include a reference list at the end of the project.
