The rep quotas for betas are lower than on graduated sites. On those, it normally takes about 3K to review suggested edits and tag wiki edits. Here, it is supposed to take 1.5K. However, I'm not yet quite there (7 points away). However, I have already made 9 suggested edit reviews.
Is this a typo on the privileges page or a bug? My guess is that it is somehow related to the new review beta.
