Re: The Official May 2012 IB Grade BoundariesI'm pretty sure that when you appeal for a remark all of the externally marked components are looked at again - so everything apart from your IAs.(Original post by Saelie)
Thank you very much! Wondering if anyone knows if I can get individual papers remarked, i.e. individual components, or is it all or nothing? -
Re: The Official May 2012 IB Grade BoundariesAlright, thanks! Do you know if the world lits count as externally marked as well?(Original post by incs)
