I just took the SA Pro exam to day and passed. The test was tough but the practice question style, answer choices, and level of difficulty was very similar to the real exam and helped me a ton. These practice exams did prepare me for the actual exam. These are a very good investment to help increase you chances to pass the exam.
There were some questions I didn’t know the correct answer for but I knew how to eliminate the wrong answers because how I read the solution to the questions in the practice exams and focused on why the wrong answers were incorrect.
