The charging standard of papertime online modification function is calculated according to the number of modified words, not according to the duplicate checking rate of the whole paper. Specifically, if the revised sentence has 38 words, then the penalty will be deducted according to 38 words. This deduction method is similar to the charging standard of most paper duplicate checking systems.

In addition, the online revision tool provides one-stop service, including manual revision and online revision. The unit price of manual revision is between 60~ 100 yuan. Talk to the paper revision teacher directly. There is no intermediate price difference, only efficiency and quality.
