FAQs
How is this different from the full practice exam?+
This is a free 20-question quick check drawn from a 65-question bank. The full-length Cellular IoT Engineer practice exam is a 65-question, 75-minute timed benchmark with a 65% target score, included with the Pro subscription. Neither awards a certificate.
How accurate are the questions?+
Each is reviewed by TELCOMA's curriculum team and references 3GPP specs where applicable. Difficulty matches the full-length practice exam.
Can I retake?+
Yes, unlimited retakes — each draws fresh questions.
Do I need an account?+
No to take it. Optional at the end if you want the personalized study plan emailed to you.
