August SAT Subject Tests 2017

When will the August SAT Subject Test 2017 registration be open?

bump. Does anybody know the answer? If somebody remembers when October opened in 2016 we could possibly just subtract 6 or so weeks from that to get an estimate.

before July 28

Thank you @annamom. It appears that they just opened up registration for some of the 2017-18 dates!
