I took IA+PM in August with the "likely to pass" feedback and the official results matched. I spoke to CLARB after the results were released - they said if you get a "likely to pass," you are in the clear for official results. There's a better chance of receiving a "likely to fail" and then receiving a PASS once official results are released. There's no receiving "likely to pass" then a FAIL.
Hope this helps! Best of luck everyone!
