Reading score changed when detail score came

When we checked on Jun 27th the Reading score was 770 and then it changed to 660 when the detail score report came after 2 weeks. Have any of you faced this issue. I have called many times College Board but no help at all. Anyone faced similar issue and got resolved?

I had a similar problem on the October 2015 test. The initial online report showed my reading score as 660, but now the detailed report says 600. All my other scores are the same.

I’m calling College Board now, but did you get any information about what happened?

been going in circles with College Board for 2 weeks now. They won’t even address the question just keep saying they will look into it and get back to me within 48 hrs… over and over again.

Has anyone had a similar experience? I saw one other member had the same type of seemingly random score drop between the initial and detailed score report. I just want to understand why it happened.
