Whenever I think about the passing chances for level 3, I wonder how many of the failing candidates chose to sit for the exam again?
About 50 out of every 100 candidates failed last year. If we put the probability of retaking the exam at 80%, this means that of the previous 50 candidates who failed, 40 (50*.8) will sit again for the exam. Since they are more prepared, both in terms of the amount of time they spent on the test and because they have the experience of failure, which can be a great motivator, about 80% of those forty will pass the test on the second try. In other words, 32 of the 40 people who retook the exam will pass it.
This means that the chance of passing for a first-taker is only about 18% (or 30% in Bayesian terms) in a room with 60%first-takers and 40%retakers. I just don’t see how a first-taker can overcome these odds while having a full-time job, family, etc. Unless you’re laid off, or have a very permisive work schedule, it seem like the format of the test sets you up for failure on a first-take.
