One of the most common questions on r/CompTIA is "I scored 75% on a Dion practice exam—am I ready?" The honest answer requires understanding Dion's deliberate difficulty calibration. Unlike practice tests that mirror real-exam difficulty (giving candidates a false sense of readiness), Dion engineers his exams to be measurably harder. This page documents the actual difficulty gap across Security+, A+, Network+, CySA+, and PenTest+, the score-to-pass correlation reported by hundreds of candidates, and how to interpret your own scores.
Yes, Jason Dion practice exams are intentionally calibrated 5-10 percentage points harder than the real CompTIA exams. This is by design. Dion has stated in course Q&As that he wants candidates over-prepared, not under-prepared. The practical rule: if you score 80% on a Dion practice exam, expect roughly 85-90% on the real exam. If you score 70% on Dion, you're borderline and should study more before testing.
Why Dion Designs Harder Practice Exams
Dion's instructional philosophy is "train above the level you'll perform at." His practice exams use more nuanced wording, more "best answer" (not just "correct answer") questions, and longer scenario stems than the actual CompTIA exam pool. The result: candidates who consistently pass Dion exams find the real test feels easier and shorter. This calibration is a feature, not a bug, but it confuses candidates expecting a 1:1 simulation. The trade-off is that scoring 75% on a Dion exam doesn't mean a 75% on the real exam—it usually means an 80-83% on the real exam.
Dion Score → Real Exam Score Correlation
Based on hundreds of self-reported passes and fails in r/CompTIA threads from 2026 and the previous year: candidates scoring 85%+ on multiple Dion exams pass the real exam ~98% of the time. 80-84% on Dion = ~92% pass rate. 75-79% on Dion = ~75% pass rate (uncomfortable margin). 70-74% on Dion = ~55% pass rate (coin flip). Under 70% = roughly 25% pass rate. The "safe zone" is consistently 80%+ across at least three different Dion practice exams in a row, not a single lucky 80%.
How to Use Dion Scores to Decide When to Test
Take Practice Exam 1 cold (no studying) to establish your baseline. Don't panic if it's 50%—that's normal. Study and re-test on Exam 2 after 1-2 weeks of focused review on weak domains. Aim for incremental gains (target +5-10 points per exam). When you score 80%+ on three consecutive Dion exams without retaking the same one twice, schedule the real exam within 7-10 days. Waiting longer causes knowledge decay; testing earlier wastes the over-prepared margin you built.
Pro Tips
Never retake the same Dion practice exam back-to-back—you're memorizing questions, not learning concepts.
After scoring 80%+, schedule the real exam within 10 days; longer delays cause measurable score decay.
If you score 95%+ on a Dion exam, you might be memorizing—rotate to a different practice source to verify.
Time yourself strictly (90 min for Security+). Most failures are time-management issues, not knowledge gaps.
Review every question, including ones you got right by guessing—those are tomorrow's misses.
Common Mistakes to Avoid
Scheduling the real exam after one lucky 80% score—you need a consistent pattern, not a single result.
Assuming the real exam will feel as hard as Dion. It usually feels noticeably easier and shorter.
Skipping the question review because "I got 85%"—the review is half the value.
Comparing your Dion scores to other people's. Variance is huge; your trend matters more than any one number.
Treating Dion's PBQs as identical to real PBQs. The real exam PBQs are usually more straightforward.
Frequently Asked Questions
Yes, intentionally so. Dion calibrates his exams 5-10 percentage points harder than the actual exam. A 80% on Dion typically translates to ~85-90% on the real exam.
Consistently scoring 80%+ across at least three different Dion practice exams (without retaking the same one) indicates strong readiness. 85%+ predicts a comfortable pass.
You're likely getting confused by similar question wording across his exam pool. Move to a different practice exam instead of retaking the same one.
It's a coin flip. Roughly 55% of candidates scoring 70-74% on Dion pass. Study another 1-2 weeks and aim for 80%+ before scheduling.
Self-reports show a ~5-10 point upward shift on the real exam compared to Dion practice scores. Individual variance can be ±5 points, so build a safety margin.
Yes, immediately. Schedule within 7-10 days. Waiting longer causes knowledge decay that erodes your margin.
