Real exam format
90 questions, 90 minutes, no inline feedback, exam-quality questions. Matches the actual CompTIA exam interface so the real test isn't your first time seeing it.
Practice Exam
Review your evidence before you schedule.
Full-length, timed, Pearson VUE-style practice exams with honest scoring. Results add to a Mastery Index that shows performance across RTJ questions, paired with an evidence-quality label.
What it is.
Real time pressure
Timer ticks down. You can mark questions for review. You learn how to pace yourself across 90 questions without burning out at question 60.
Mastery Index plus evidence
The index summarizes correctness across RTJ quiz and practice-exam questions. Read it with the evidence-quality label. It is an internal, uncalibrated study signal, not a pass prediction.
How it works.
- 01
Take a full-length
Pick Core 1 or Core 2. Set aside 90 minutes. No interruptions. The exam plays just like the real one.
- 02
See the breakdown
Score plus a per-domain breakdown. You see exactly where you're strong and where the weak spots are.
- 03
Drill the weak domains
One click sends you back to flashcards and quiz questions filtered to the topics you missed.
- 04
Build broader evidence
Use multiple recent attempts across the exam blueprint. A high index with thin evidence remains thin evidence, and only you decide when to schedule.
