National 5 English

For anyone who studied english at national 5 and attained a good grade, how many main body paragraphs did you do for your essay?
I'm studying Curley's wife in Of Mice and Men, and currently I have four main body paragraphs - talking about her flirtatious presentation, the fact she's only named 'Curley's wife', her loneliness & isolation, and her failed dreams. With an introduction and conclusion as well, would four paragraphs be enough to get me an A in the final exam? I used PEEL and have at least two quotes and two explanations in each paragraph, I stated what each technique used was and covered things like contrast, sentence structure, characterisation, etc. Is this enough?
