THE VCE exam body has apologised and promised no students will be disadvantaged after a doctored image depicting a giant robot assisting socialist revolutionaries in 1917 was accidentally used in a history exam.

It is the second year in a row the Victorian Curriculum and Assessment Authority has been forced to apologise following debacles in the end-of-year exams.

The image that appeared on the exam paper.

New guidelines governing the use of internet-sourced material in exams will also be issued after an altered version of the artwork Storming the Winter Palace by Nikolai Kochergin appeared in the VCE History: Revolutions exam.
