What it takes to pass Security+

SY0-701 reports results on a scale from 100 to 900, and 750 is the line on that scale, not a percentage of questions. CompTIA converts your raw performance to the scale with a model it does not publish, which weights questions by difficulty. Two candidates can answer the same number of questions correctly and land on different scaled scores.

That has one practical consequence: nobody outside CompTIA can tell you exactly how many questions you can miss. Any site that gives you a precise miss budget is guessing. What you can do is practice against the same cut score: our Security+ practice exams score on the published 750 line, so a practice result reads the same way the real one will.

No waiting period before your second attempt. From the third attempt onward, CompTIA requires a 14-day wait between attempts. A retake costs another $425, which is why sitting practice exams until you clear the line consistently is the cheapest part of preparing.

The candidates who pass on the first attempt treat the cut score as a rehearsal target, not a day-of surprise. Sit a full-length Security+ practice exam under the real time limit, scored against the published line, and book the real exam when you clear it consistently rather than once.
