How long should an opinion piece be? Do you get docked marks if its too long?
they say 80-150 words, but you're unlikely to score well if it is too short. Aim for 150. Most of mine are a page long with 3 central paragraphs. No marks are docked for length as long as you stay on point and don't meander. Also due to time constraints it might be difficult to write too much.
I agree with ebkg, write as a much a s possible and use as many verbs and phrase as possible and show off your vocabulary
