Exam Scoring
There is no penalty for wrong answers, so if you are stuck on an answer, use your best judgement and process of elimination. Remember not to get bogged down by one question, move on and come back to it if you do not immediately know how to solve it.
Passing Score
The passing score is not published, since the exam is scaled through psychometric statistical calculations and not by a specific passing score or rate. However, the concensus from test takers answering around 50-55% correct. The pass rate for the CBT exam as of January 2021 is 75%, which means 75% of test takers passed.
Exam Scoring
The scoring is done by ranking a bank of questions based on difficulty, and comparing the scores against what is expected to be the minimum ability of the engineer. This has been determined by subject matter experts.
