I built a free certification exam readiness calculator.
If you're studying for CompTIA A+, Network+, Security+, CCNA, CISSP, or similar — this tool tells you whether you're actually ready to sit for the exam.
Enter your estimated performance per domain. The calculator weights each domain the way the real exam does and gives you an honest readiness score. It knows that not every domain carries the same weight, and that you don't need 80% across the board to pass.
No account required. No email capture. Just an answer.
Most people study until they feel ready. This gives you data instead of feelings.
