Thanks for asking, I'd say it was easier than expected. I studied mostly from
https://www.citizenshipsupport.ca (I had to pay for the subscription which gave me 600+ questions that covered every single item in the book. The exam questions were quite similar to what I prepared - highly recommended!).
The interview was straight forward, but in my case, the officer focused a lot on my travels since I have been out frequently, especially to the States. Gladly I was well prepared and had printed my i-94 history which she asked if she could keep.
I'm still waiting for my status to change to Decision Made. I'm assuming there will be some delays there until they verify my trips and probably go through a security check...
How about you? What's your current status?
