@lindyk8 I just talked to a counselor who seemed to be fairly well-informed. He thought that IGETC was some, er, ultimate thing, such that when IGETC is certified, no institution really tries to go back and invalidate it. It is at the discretion of the CCC to clear IGETC. If that is the case, then I should be fine, as the AP units certainly fulfill IGETC requirements. I’m still wary, though.
He was going to talk to a TAP coordinator at Berkeley for more reliable information, and I’ll be in contact with him. I may drop by Berkeley’s transfer center tomorrow to ask them this, too.
