The number of words in a paper is not as large as possible. You wrote 20,000 words out of the 5,000 words required by the school, which is obviously a bit much. But this is not absolute. You can discuss it with the teacher and listen to his suggestions.

Generally speaking, if you need 5000 words, there is not much problem in writing 8000 or 10000. If you write too much, explain the content in detail, and the teacher agrees. It is also a good thing to write too much.

I suggest you ask the teacher's opinion first to see if there are any repetitions or redundancies in these nearly 30 thousand words. You can delete unnecessary content. It's best not to delete it yourself, but to listen to the teacher's advice.
