Number of Questions: 80 questions in 170 minutes
The questions are long and detailed, most of the questions will take around 1 min to read & comprehend. You will hard get time to go back and review. So during the exam keep and eye on the watch and when you practice do time management.

Professional exams are harder than associate in a sense because in Associate you will usually get obviously 2 wrong answers and 1 one close one and then the correct answer. In Professional exams most questions have equally possible answers and you are suppose to pick most suitable one. Hence you need to read the question carefully, because one word can have different answer. Also in the exam there were will be some misleading clues which you need to ignore. It’s very important to practice as many questions as possible to get used to not making mistakes.
Scaled scoring models are used to equate scores across multiple exam forms that may have slightly different difficulty levels. 70+% is a safe score.
