Radar19:
I’m creating a CIC profile now. Can I take that English test online or do I have to attend a classroom session?
You do it in a classroom under exam conditions.
The results only last 2yrs in Canada, (apparently, you lose the ability to speak the language after that) and if the 2yrs is up before your PR is being processed, you have to re-take it.
If you have to take it then wait until you are almost ready to send your PR app in.
There are apps available for smartphones for practise tests for both Ielts & Cel-pip.
Cel-pip is only recognised in Canada but Ielts is recognised all over the world.
