Just wanted to share my experience. I appeared for CELPIP 3 times (@toronto), listening and reading scores were 12 or 11, writing was 8 and speaking stayed 6 all the time, I was very confident on my 3rd try (even did a re-evaluation), but speaking score wouldn't go above 6. I feel they are harsh on giving score for speaking. Finally after wasting over 1000 bucks on CELPIP I tried IELTS, this time didn't prepare for listening and reading just watched some videos on speaking and writing ( I found E2 IELTS on youtube really helpful) the score was L8, R8.5, W6.5, S7. From my experience, listening and reading topics are comparatively tough for IELTS, writing is more or less the same and speaking is easy on IELTS. For overall good score I would suggest IELTS
