To get a better idea of how to write an essay, try to imagine that someone suggests that you think of a word like "
is myhomeworkdone legit." Immediately associations like: dance, Vienna, old ball, school waltz, first waltz, your own memories, as well as quotes from classical works will begin to arise.
Thus, in the process of writing your essay, you will realize that such a listing ties together the pictures that emerged, and you will finish it only when the flow of associations stops.
When thinking about how to write a good essay, read the examples of previous years in advance and take the techniques you particularly like.
First, write down everything that arose in your mind when you read the text. Then select the main point and tell it as if you were the first person to talk about the problem. Be convincing, logical, concise, moderately emotional. Don't forget your sense of humor.
When the draft is ready, reread what you've written:
through the eyes of a child (everything should be understandable even to a toddler);
through the eyes of a peer (does the text make you yawn? Rewrite it!);
through the eyes of your teacher (whether the essay you have written corresponds to what the teacher has prepared you for).
Then forget about all three readers and just make it so that you personally like the text. Would you recognize your essay if it wasn't signed? Okay, give yourself an A!
