1, if you can't write well, you will.
Whether you want to make a big change depends on whether your paper is reasonable or not. If you send the topic and outline to the teacher for review before writing, even if you make great changes later, it will not change the framework, only the content. But some teachers are in trouble if they don't show you the outline. If the writing is not good, the teacher will have many suggestions for revision, and the probability of major revision is very high.
If you write well, you don't need to make great changes.
If your paper is well written, at most, you can change some of the contents, and everyone can accept it, and at most, it will be within 2000 words.
Some people may only find fault with you.
It is not excluded that the teacher will ask you the question of format only if your duplicate checking rate is qualified. In this case, you should thank the teacher, so the first draft should not be too perfect in format. Leave some questions for the teacher to point out, and then do the content well to avoid big changes.
When the framework of the paper is set up and the content is filled, it can be handed over to the tutor. Throughout the full text, carefully check a series of small details such as format, narrative method and data rigor (this will make the paper more standardized and leave a good impression on the teacher! ), and then give the first draft to the teacher.
Generally speaking, the first draft of a paper is changed the most, so when the paper is finished and handed over to the tutor, the tutor will not take the exam. The teacher is only responsible for correcting the problems in the paper and needs to detect duplication by himself. Teachers don't help to find duplication.
