3. Clean Writing
Tutors would all say the worst essays submitted are nearly always from people who have problems with basic grammar and spelling. An essay is a professional piece of writing. The occasional grammar mistake is acceptable. Having a piece of writing littered with basic spelling errors and misplaced capital letters is one way to descend to a new academic low.
It doesn’t just highlight the writer’s immaturity. It detracts from what they’re trying to say. What authority does someone have when they can’t even express themselves in a coherent way?
Whilst drafting, there’s no need to worry about your grammar and spelling. Leave this until the end. Teachers see correct grammar and spelling as a standard skill, therefore they expect to not have to swim through a sea of mistakes. Content always comes first. Concentrate on grammar and spelling on your final few edits.
