Ugh, you cannot compare grade boundaries like that, harder papers receive higher grade boundaries and easy papers have high grade boundaries. When I say it will make grade boundaries increase, I mean when the examiners are setting grade boundaries they take threads on forums like TSR into consideration. Also grade boundaries are set by taking into consideration how well students do overall, if the paper is leaked on TSR it is inevatble people who do the exam on the second day onwards will do really well, so the grade boundaries will be higher. And how do you know if your brother didn't leak the paper the boundaries wouldn't have been lower. honestly don't understand why people get so defensive, I'm only saying its best not to leak the paper as it would be classified as cheating, it's better to be fair and just, and that is the teachings from your religion Ahmed, i shouldn't have to be telling you this!
