You can guess it from the simple fact that compared to Java 17 Professional Exam 1Z0-829, this certification have more time, 120 minutes compared to 90 minutes for solving same number of questions, 50. Why would they give you more time? Well because each questions is much longer, lengthy, complex, and have up to 4 to 10 options to choose from.

Because of that, even after adding 30 minutes, many people will struggle to solve 34 questions correctly which is required to pass this exam.
