Done test on 24 feb was straight forward . got 19/20 and my wife got 18/20. waited for interview for over hour and it took only couple of minutes for officer. she took photocopies of our passports and told us she cant make decision as of now as she needs to check all the stamps in our passports and i can except a reply in 2 to 4 months for oath if everything is ok.
i know thats there standard answer but cant do anything have to wait.
for test prep go through discover canada thoroughly if you dont know abt canada history as my wife got test based on history most of it. she said it was tricky. and apna toronto tst papers are really good as well.
Thanks
