Thank you jonnyboat and carlston49 
i know it isn’t but i felt the test afterwards was just impossible and it put doubts in my head that i had easier block of questions this time and next time might not be so lucky! 
i might give the app a go then. Did you pass first time jonnyboat? Thank you carlston i realised at least 2 answers i got wrong straight afterwards. What edition was the theory book you used? Seems that on Amazon they stock several versions
