Order of body paragraphs/examples in essay writing

So, quickly, my credentials:

• When I was in high school (admittedly quite a few years ago), I took both AP English courses, passed with 5s, and wrote many persuasive essays with excellent teachers who frequently had extremely high passing rates.
• As a high school student and for a few years after, I tutored students for the SAT, including the essay section, and have had students go from scores in the 10s to scores in the 20s reliably.
• I still to this day beta read and edit student essays.

The comments indicate this was originally for an examination, so it is with this experience that I would recommend starting with the smallest scale example and work your way towards larger.

When you write your thesis statement, you will have to include all of your basic arguments are in it in the order which they occur in the essay. So, your introduction will include the most global example and it will be the final and, thus, most memorable part of the thesis statement. Your reader will not have to slog through your personal example just to know if there's anything else.

(I know that phrasing sounds a bit harsh, but as a reader I've seen many students fall for the trap that their interpretation of a meaningful event in their lives translates to an effective argument. You have to prove that it does with evidence.)

If a reader is not convinced by your first argument, they may be tempted to skim. Teachers, professors, teaching assistants, and standardized test graders all have many essays to read. If their skimming is rewarded with bigger examples with meatier analysis, they'll be more tempted to stop skimming and continuing reading. If their skimming is rewarded with many "I" and "my" statements, they may not be as tempted because of my point above that those examples tend to be weaker and more lacking in analysis.

From there, the essay progresses nicely to the conclusion. The conclusion should include an even more macro scale argument—if possible, an attempt at a universal truth—as well as a one-sentence summary of why your arguments and examples above prove what it is you're trying to prove. This sentence will present your arguments again in the order that they were presented in the essay, so again the largest example will be the final part and leave the most lasting impression.

Based on personal experience (I have written many an English essay on how x writer shows y theme in z extract), I would say write the large scale example first, and then narrow down to specific examples. This is a very logical sequence that the examiner/reader will be able to follow very easily, and it shows that you understand the subject to both a general level and also a very nuanced level.
