I’m confused by what you meant. When I emailed OptomCAS they said to list all previous attempt as 0 for credits and to only give credit for the most recent attempt as long as it’s taken at the same institution. They didn’t say there was a limit on just the first two attempts. I’ll attach the email I received from them. I even emailed back asking in a case where I’ve retaken the class 3 times, and they said it’s still the last attempt.
