If it is the first draft, you can find some free software to query, and the final query will cost money.

For example, we need to charge for duplicate checking on HowNet, and the price is relatively expensive. But most schools will give you one or two free duplicate checking opportunities, so make good use of the free opportunities and don't use them casually. We'd better use other testing systems to revise the first draft, such as checking the duplicate of the paper, and then take it to the school for testing. This is how I check for repetition when I write my own paper. I can use the free duplicate checking software at first, but his modification is still mechanical and needs my own comparison. If anything goes wrong, I corrected it myself. If the school doesn't provide free testing opportunities, you have to pay for the testing yourself. You can check the repeated networks in the quick paper.

You'd better not ask others to help you write the paper, but do it yourself. Generally speaking, the prices of VIP, Wanfang and paper are almost the same for the first time. As long as we really write word by word, we can pass the first time, and the last time is more important. It can be said that the duplication of this paper determines whether you can graduate smoothly. I suggest spending some money to check with HowNet. Although it will be more expensive than the previous ones, HowNet has passed and there will be no problem in avoiding it at school.
