Can I take CELPIP exam again?

Short answer: Yes, but not right away: you can take CELPIP again 30 days after your previous test. If you register again and test within those 30 days, the new test is cancelled.

 No. After the first exam, you can take the exam again after 30 days. If you re-register and take the exam within 30 days, the exam will be canceled.
