Keep It Simple Students!
- you will make less mistakes (grammar, structures, spelling, punctuation etc).
- easier for you to write (easier to translate from your mother tongue).
- you can avoid giving headaches to the reader (the examiner).
You are human, the examiners are human too. Make it easy for them to mark your paper, they will make your life easy by giving you the good marks that you deserve. So, remember K.I.S.S!
