I want to have a comment of seniors on that how important is it to write an essay in a traditional way. I mean opening an essay with a thesis statement and then proceeding with the conventional arguments explaining the topic and the main idea. Then going to the analysis of causes, factors, repercussions, remedies, solutions and conclusions.
What if a person writes it in a bit different way, I mean to dramatize the opening or starting with a example then inferring/extracting the main idea from that example. Here,intention is being to involve the reader rather than to express the command over language.
I have heard from a teacher that standing out from the crowd and innovation are the requisites for English Essay be it in terms of expression, vocabulary, idea or writing style. I am a bit reluctant to comply, seeks your advice.
Another thing. Is it okay to write example from one's own life ? (Yes ! only when they are most suitable and cohesive).

You have asked a very good question. As per my experience and knowledge, I'd say you if you want to dramatize then it would be more appropriate if you start from the historic perspective of your topic. But do it only if you have a background knowledge about that topic. But, again be careful to remain on the track. Don't write it too long and your sentences should be inter-related because you are going to hit the bull's eye after giving that example. Whereas causes, factors, recommendations and conclusions are the skeleton of every essay so don't skip them.

Regarding your second question, it depends on the topic. One advise from my seniors that I learned that don't ever try to impress the checker. For making impression, you have rest 11 papers. Essay is the only one question with merely one right answer. So, be careful and choose that topic on which you can easily write.

Stay blessed.

Regards.

On average the checker has 7 minutes for your Essay so it's advisable to open your Essay with thesis statement; the idea is to facilitate him and save his time, tell him in your introduction that on what side of argument you are.

You should dramatise your opening only if your dramatisation is interesting enough to mesmerise the checker. You should bear in mind that what is intriguing or dramatising for you might be dull and wastage of time for the checker. It would be a risk but as they say " greater the risk greater the return "

How do you know that on average the checker has 7 minutes for our essay ? Is it your guess or what else ?

Checker has 6 months to check the Essays. He or she is working in Government university. On average he spends 8 hours a day on Essays. Now do the math and results would be around 7 minutes

I would advise against any kind of deviation from the conventional approach. It is too big a risk. As Monk said, examiners don't have time to read through all your dramatisation. He just wants to know right away about what you're gonna be up to in your essay and whether you have been on point using proper English along the way.

What about quoting examples from a variety of fields like science, sports, business and arts. I am asking because I got my one essay checked and the feedback I received from teacher was that quote examples only when they are relevant. I argued (harshly,out of paroxysm, because he had failed me) that I have quoted an example from football which seems quite homogeneous with the subject and perfectly serves the purpose here. "Only quote examples from history, political or religious, other wise write some wise (not expected of you) quotation. Don't give examples to which examiner couldn't relate or find it difficult to discern. Don't bring examples from cosmos. Okay. Now take your paper, go away(get lost)", my teacher responded.
Now, I ask you to please evaluate his advice according to your experience.

The CSS examiners have the same psyche as the guy who checked your essay. Follow his advice to the letter.

Your teacher has rightly advised you. But, like he said, starting with religious examples certainly doesn't mean that you support or deject school of thoughts. It could be dangerous for you if you do so even in Islamiat paper. Having said that, depending upon the topic, you can start the essay with aforementioned things. My mentor Sir Tashfeen Alam (PAS-42nd batch) told me that one can start with historical background only if he is profound with its knowledge. Stating with examples requires consistent practice of essays with said writing style. Lastly, don't do any experiment in exam ! Use simple and correct English as well and be on the track of the topic.

Good luck.

Stay blessed.
