Passed the test today (18/20 me) and (20/20 wife) at Scarborough. Joint interview with my wife. The officer found a minor mistake on my "Physical Presence Calculator" and asked me a couple of questions about it. He asked me to make the change manually and then initial it. A couple of other questions about my employment, passports and usual questions like the date of landing, address etc. Test+interview+waiting time before and after the exam was 1.5 hours.
Like
@stalintouch above, the Officer said the date for the Oath will be between now and Oct-2018 (I applied in Oct-2017).
