The CELPIP is quite an easy exam to be honest. Just do a lot of practice and understand concepts (e.g. exam structure, rules for writing,), what to look out for in the exam and you will do well.
I did mine in March and I scored:
Reading- 12
Listening- 12
Writing- 11
Speaking- 10
Thanks! I am not generally worried, except for speaking because it's my weaker area.
