    A large number of posts have been removed from this thread due to discussion of the June 13th Calculator exam. Please refrain from discussing ANY Edexcel exam until either 12AM for AM exams or 4.30AM for PM exams. Edexcel exams are taken all over the world, and so by discussing them you are possibly giving other students an advantage over those who have already taken the exam.

    For more information, please see the announcement.
