What is the passing score for Security+?
750 on a scale of 100 to 900
Security+ is graded on a scaled score between 100 and 900, and you need 750 to pass. A scaled score is not a percentage of questions answered correctly: the vendor adjusts for how hard your particular set of questions was, so two candidates with the same number of correct answers can end up with different scores.
This is why you should ignore any site that turns this into a percentage. The scale starts at 100, not at zero, and the points behind it are not distributed evenly.
What this means for your preparation
You cannot convert 750 into "answer N of 90 questions correctly", and nobody outside the vendor can. What you can do is aim well clear of the line and know which domains are dragging you down.
