yeh, I wouldn't advice talking about all the sectors of pharmacy since it is supposed to be a personal statement not a statement to show how much you know. I structured mine as: intro - sumthing I choose to pull the tutors
2nd paragraph-subjects at a-level, what skills I developed? The third and the fourth paragraphs were on about my work experience placements, and background reading. Then extra curriculum stuff and then my closing paragraph. I didn't talk to much about what pharmacy will do for me, but rather what attracts me to pharmacy and aspects that intrigued me, whilst on work experience.
