UK Citizenship

Hi guys,
I am currently an international student based in the UK, and I really liked living here when studying. However, my student visa is running out when I graduate in the summer. I am presently undertaking some tests in order for me to hopefully obtain British citizenship. There were so many websites out there, and I came across this site: http://citizenpaper.co.uk/life-in-the-uk-test/.
This is far the best one I have seen, even though I am only getting 18 out of 24, ha ha. What do you think you could get?
