To achieve Level One Formal Writing you must be able to write without intrusive errors. This is difficult for many of you and it was a problem noted by your teachers after grading the mock exams.
To be able to write at the accuracy level required you must understand the expected writing conventions. Writing conventions are the rules used to create meaning from the words chosen such as: spelling, punctuation, grammar, syntax (order and choice of words), and paragraphing. A piece of formal writing without intrusive errors means that your writing does not have significant and/or repeated error patterns (in spelling, punctuation, grammar, syntax, and paragraphing).
To achieve with excellence your writing must be accurate. That means work has been closely and carefully proofread to a near-perfect standard with limited errors, so that only minor editing is required.
