Help on the Life in the UK Test?

Hi, I am sitting my life in the UK test on 15 Feb. If I am honest I am very nervous... I am try to practice as much as I can. I have read the book three times and made notes of key dates. I am sitting questions from the official book and sites like uktestpass but I am still not sure it is enough. I can't afford to resit at the moment if I fail. Has anyone sat this recently and does anyone have any helps pls? Thank you x!
