That's it, except for correct, incorrect ones and short answers, but I'm pretty sure that's the answers to them all, hopefully, hope you now have a fair indication of how you went in the test...
With these correct answers in mind - I got 24/25 for non-calculator and approx. 47/50 for multiple choice, stoked.
If you want to know a particular question, just write back on this answers thread and I will try to show you the correct answer and working out.
