Agree strongly with M. Scroggs's sentiment re: not being bullied by parents/teachers/hearsay on PPRuNe into taking the wrong A-level subjects.
Many moons ago, I was manuvured into taking A-level Physics & Maths. Hated both of them and dropped out after 2 terms.
That experience later made me question whether my brain was wired the right way to cope with ATPL studies.
My A-levels in Business Studies, Economics & English Lit certainly haven't held me back, and am coping just fine with ATPL Groundschool, even doing distance learning with no one looking over my shoulder to help.
Would suggest actually that buying Mega Memory from Shop America [sic] would be as good as anything, because regurgitating facts is the crutial ability here.
