IST practice questions - frequently asked questions

Plain answers about how IST Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real IST exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The IST exam spans 6 domains: Project Process (6.00% of the exam); Infrastructure (12.67% of the exam); Equipment Installation (18.00% of the exam); Communication Systems (18.67% of the exam); Integrated Systems (33.33% of the exam); Systems Verification & Testing (11.33% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Integrated Systems 33.33%; Communication Systems 18.67%; Equipment Installation 18.00%; Infrastructure 12.67%; Systems Verification & Testing 11.33%; Project Process 6.00%.

The IST exam has 165 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
