Completing a dissertation typically takes between 6 months to 2 years, depending on the complexity of the research and individual circumstances. This timeframe includes stages such as topic selection, literature review, research design, data collection, analysis, writing, and revisions. Full-time students generally finish faster, while part-time students or those balancing work may take longer. Effective time management and regular progress reviews can help streamline the process and ensure timely completion of your dissertation.
