If you’re preparing for the CompTIA A+, ISC2 CC, or ISC2 SSCP, you’re probably already taking practice tests. But here’s the question that separates candidates who pass from those who retake: what do you do with your wrong answers? Reviewing wrong answers on practice tests is the single highest-leverage study activity you can do — and most people either skip it entirely or do it in a way that doesn’t stick. Let’s break down exactly how to turn every missed question into real exam-day confidence.
Why Wrong Answers Are Your Most Valuable Study Material
It feels good to breeze through the questions you already know. But correct answers don’t tell you much — they just confirm what you’ve already got locked in. Wrong answers, on the other hand, are a precise map of your knowledge gaps. Every time you select the wrong option, you’re getting a signal: this concept needs work before exam day.
The CompTIA A+ Core 1 (220-1101) and Core 2 (220-1102) exams each contain up to 90 questions, require a passing score of 675 (on a 900-point scale), and give you 90 minutes per exam. The ISC2 CC exam has 100 questions with a passing score of 700 out of 1000. Every point matters. That means every wrong answer in practice is a gift — an opportunity to close a gap before it costs you on the real exam.
