There is a button “Request a revision” next to each order that you have ordered from us. Our company offers two options for sending a revision request: a free option and a paid option. In the former case, you are limited in time. When the paper is short (up to 20 pages), you have 48 hours for sending a free revision request. When the paper is long, you have 30 days for sending a revision request for free. Remember that revision does not mean sending new instructions. Especially when you want to use the free revision option, you should not modify the initial instructions. Nonetheless, you need to provide specific revision remarks and specify by what time the paper should be revised.
