1. Lack of Clarity: Green ink may not provide the necessary contrast on standard examination papers, making it harder for examiners to read and grade your answers accurately.
2. Confusion with Graph Lines: Some examination papers may have pre-printed graph lines or grids in green, so writing in green may lead to confusion and make it difficult for examiners to distinguish your answers from the printed lines.
3. Standardisation and Optical Mark Reading: Many exam boards use optical mark reading (OMR) systems to process answer sheets. OMR systems are designed to recognise and capture data from specific marks made by black or dark-coloured pens. Green ink may not be effectively recognised by OMR scanners, leading to potential errors in marking.
4. Exam Board Guidelines: Most exam boards have specific guidelines and regulations regarding the use of pens and writing instruments in exams. These guidelines typically recommend using black or blue ink, as they provide the best clarity and contrast for marking purposes.
To avoid any potential issues or confusion, it's always advisable to follow the specific instructions provided by your exam board or school regarding the use of coloured pens or markers in exams. If in doubt, it's best to stick to the recommended black or blue ink to ensure your answers can be accurately marked and graded.
