Common questions

How many exams and questions are included?
12 full-length exams at launch — 6 for Server+ (SK0-005) and 6 for Network+ (N10-009). That's 720 unique practice questions.
Is the question content current?
Yes. All questions are written for the current exam versions: Server+ SK0-005 and Network+ N10-009.
What does the AI tutor actually do?
It's powered by Claude. You can ask it to explain a domain, quiz you on specific topics, or clarify why an answer is correct. It's scoped to the two certs — no off-topic drift.
Can I cancel anytime?
Yes. Cancel from your account dashboard. Access continues until the end of the billing period.
Do practice scores match real exam scores?
Each practice exam uses the real CompTIA passing threshold (typically 750/900) so your score is directly comparable.
