For lecturers/teachers/exam markers:

When marking a repeat, do you generally want to see the student pass if their new script genuinely reaches the standard, or are you completely detached and just mark it exactly like any other exam?
If someone got 35-39%first time, then studied properly, fixed the grammar mistakes that were costing them marks, and their repeat is borderline (39–40%), would you tend to look carefully for legitimate marks that could put them over the pass?
Also, do markers actually notice when a student’s writing/grammar has improved from their previous attempt?
