FAQ
Is the free exam really the full thing?
Yes. Ninety questions, the full time limit, weighted across every domain, with unlimited attempts. It is the same simulator included with a paid trainer.
Is this a subscription?
No. One payment per trainer, no renewal. Access includes the purchased certification trainer and future updates for that certification while CertTrainer operates and supports the trainer.
Why is A+ one purchase for two exams?
A+ requires passing both Core exams, so a single payment covers both.
Do I need an account to start?
No account is needed to practice. You will need one to purchase, so your access follows you between devices — and you can create it after paying.
What if it's not what I expected?
Email us within 14 days of buying and we'll refund it in full — no questions asked. Access to that trainer ends when the refund goes through, and nothing else about your account changes.
Are these real exam questions?
No. Every question is original, written against the published exam objectives in the same style and weighting.
