Coursera typically enforces deadlines for course completion, but it varies depending on the course and its specific policies. Many courses offer a flexible schedule, allowing you to work at your own pace within a certain timeframe. However, exceeding the suggested completion time by 6-7 weeks might pose challenges. Some courses have strict deadlines for assignments and assessments, which could affect your ability to earn a certificate if you fall significantly behind. It's essential to review the course details and contact the instructor or Coursera support to understand if extensions or alternative arrangements are possible for your specific course. In some cases, you may be able to apply for a course extension or retake the course in a future session to earn a certificate.
