Will writing more essays help me increase my score?
Not necessarily.
Your score is determined by your mistakes, so if you write 100 essays but you make the same mistakes in all of them, your score will not increase.
The only way to increase your score is to stop making mistakes.
Think of it this way:
- you don't know how to correctly use articles and punctuation, so you make mistakes and you get a Band 6 for Grammar
- you write 100 essays with article and punctuation mistakes
Is your score going to go up? No. You will still get a Band 6 for Grammar.
So, what should you do instead?
