First Assignment Reviews (FARs) are a top priority in the review work pool. However, reviewers are also contractors with flexible work schedules. All contractors have 7 days from the date they check out work to complete it.
Typically, FARs are checked out and reviewed within a day or two. It's not uncommon for writers to get a FAR returned for correction, since the purpose of the FAR is to ensure you fully understand the project requirements. If your FAR hasn't been approved or returned within 7 days, please submit a help ticket to the in-house team so we can look into it.
