The Answers will show with explanantions of how to calculate the answer after you complete and submit. This is a 12 question exam like the real thing, where you will have 12 questions in each of the 5 sections for a total of 60 questions. So if you want to check your timing, you should be able to do this exam in approximately 10 minutes, because Equipment is less time consuming than Physics or RDP so being able to do this one fairly quickly will allow you more time in the other more time consuming sections.
