While there is no specific answer as to whichever test is easier out of CELPIP vs IELTS vs PTE, IELTS tends to have greater resources, more practice tests, and more experts to help you prepare. However, CELPIP is often easier to take and can be shorter, depending on your abilities. PTE tends to be more interactive. However, how this compares to the other tests can only truly be determined once the test is open.
