I am alomost 99% positive that DD1 would have passed without
.However she had never sat any other kind of exam unless you count dancing! It would have been an almighty risk not to have even shown her a few papers, which is all we had time to do, as we had a sudden house move.She could have been the type to buckle under pressure and need exam techniques.
She too went to state school like DD2 and probably would have made it regardless.However , as said before, that is because she took HERSELF further in maths.Also many state schools do no real exam practice, ie long papers back to back, until year 6 SATS.
I think it is a rare child who could pass without prep.They have to be extremely bright, have a good mathematical coverage from whatever school they have been to and be natural at speed in VR.Here in Essex it is 80 questions in 50 minutes, with many code kinds in the real thing , which take longer.The English is KS3 standard comprehension .
I am not saying it is impossible but why risk it if you can access the papers.I am not talking 2 years and hours and hours
I wouldn't expect a child to walk into any other school exam without any knowledge of what was coming.
Anyway , have a nice day - off to work now
