This is great! I scored 60% because I didn't realise 5321 HELO was also checked. That's news to me, I've never seen that before. I got 90% on my 2nd attempt :)

Also I think there was one question that was a mistake, it had a policy along the lines of:

v=DMARC1; p=reject; <stuff...>; pct=0; <stuff...>

I answered that a failing message would have an effect of p=none, but the right answer was apparently p=quarantine. Is that right, considering pct=0? (Unless I was blind and the pct wasn't set to 0 in the question...)

https://datatracker.ietf.org/doc/html/rfc7489#section-6.6.4

"If email is subject to the DMARC policy of "reject", the Mail Receiver SHOULD reject the message (see Section 10.3). If the email is not subject to the "reject" policy (due to the "pct" tag), the Mail Receiver SHOULD treat the email as though the "quarantine" policy applies. This behavior allows Domain Owners to experiment with progressively stronger policies without relaxing existing policy."
