In Balochistan PCS Exam, we have to write 450-600 words and mostly essays are quotational/maxims, let me give some examples...
Beauty is skin deep

now i want to ask, by giving its meaning, expanding its idea, how many paragraphs I should write for the said length, plus what about techniques? topic sentence, body of paragraph, concluding sentence? how can I controll one idea in one paragraph, it may require many ideas in different paragraphs?

Seniors, please as per your experience, give me a little idea, what examiner sees mostly in such quotational and maxim essays of a candidate.. thanks
