Thanks a lot for that, but unfortunately this is 2009 when A* wasn't introduced lol. So my question is, if a candidate satisfies all the boundaries to get an A in all of the 4 papers, is that an A*? Or are higher boundaries set for a candidate to achieve an A* grade? Either way I cannot change anything lol, but it would be helpful to know, because I haven't been able to tell the difference in terms of marks between an A and an A*. Thanks again, those boundaries really helped!
