&gt; Moreover, when I was studying would I have ever had the balls to contact my lecturers and not only question their ability to grade my work appropriately but imply that my low grade was their fault?<p>It&#x27;s not surprising that students want to get a second opinion on grading.<p><a href="http:&#x2F;&#x2F;www.bbc.co.uk&#x2F;programmes&#x2F;p03bqlht" rel="nofollow">http:&#x2F;&#x2F;www.bbc.co.uk&#x2F;programmes&#x2F;p03bqlht</a><p>&gt; More than 90,000 GCSE and A-level results were changed after challenges to grades awarded this summer - the highest on record.<p>&gt; The figures represent an increase of 17% compared with last year.<p>&gt; Results have a significant impact on both students and institutions, affecting whether or not pupils gain a university place and where schools appear in league tables.<p>(GCSE exams are taken in school by 16 year olds.  A level exams are taken in schools or colleges by 18 year olds, and are what is used to get entry to university.)<p>EDIT: In 2013 there were 850,752 GCSE exams taken.  So 90,000 incorrect grades is more than 10% - and these are just the exams that asked for a re-grade.  When students have seen a serious error in their grades, or the grades of a friend, it&#x27;s not surprising that they realise that just asking for a regrade could increase their marks.
