You get paper to do the working out on but the test is on a computer. No mental long divison required.
I have got the Trachtenberg book you mention and although it’s interesting if you’re into that sort of thing I found it useless for the test, it’s full of new techniques for mental arithmetic which you don't need.
Just make sure you can do long division/multiplication, conversions for ccys, some basic fuel calcs(no prior knowledge needed), and some square/cube roots if I recall.
Best bit of advice I’d say is know all your times tables, if you can reel them off quickly it speeds you up no end when doing division/multiplication questions.
