Hi Yas, welcome to EF!
To be honest, I have felt confused lately while reading your thread. I have no idea how to give a proper response to this "short" and unclear thread. I am just afraid that the moderator of this forum would suspend you if you create such an unclear thread. I have read this thread several times and still couldn't figure out what should I say. However, I would like to analyze them now. I hope you can still follow through.
First thing first, it is your title. I assume that it is a "question", and you need an answer for that. Therefore, my answer would be:
- An essay about the essence of progress can be off-topic if you talk beyond the limitation. There has to be a limitation for all types of essay. Essay is not a book. Even a book itself has its own limitation of discussion. I assume that one type of essay that related to essence of progress is IELTS task 1. In IELTS task 1, when the candidates want to write about a progress, they cannot write any opinions related to the progress itself. This is not appropriate because they are supposed to only REPORT the information by selecting/describing the key features, stages, or differences, and they are NOT allowed to write any opinions. If this was type of essay that you've meant, I am glad that it will be helpful.
Second, please explain MORE CLEARLY about this:
"I had, in my opinion, a philosophical subject for an English written exam." (then, what is that? a philosophical subject like what?)
"I wrote about the innovations of human so far, and then I developed the idea that necessity leads to innovations, also, innovations or discoveries because of specific purposes or conditions." (then, where is the essay? I think you need to upload the essay first then we can discuss it further.)
That's it Yas, sorry for taking quite a long time to respond because your thread was unclear. I hope to see your respond soon.
