SAT after June 2015

I’m going to take 2 subject tests on June (Chem and Math 2), but I’m worried that I might not get the score I want — it seems like June 6 is the last test date for 2015, is that really the case? All prior years have Oct, Nov, Dec test dates. If that’s the case, what should I do in case of an unexpected grade on the subjects?

Thanks!
