In the FAQ that was released last November it says:
Exam Experience:
Q: How does CBT change the format and style of questions on CAS Exams MAS-I, MAS-II and 5 – 9?
A: While the CBT environment can allow for more sophisticated test questions and the use of larger datasets in the future, those changes will not be implemented for the Fall 2020 exam. The CAS is focused solely on the transition from paper and pencil to a computer-based delivery format at this time. The questions on CAS Exams MAS-I, MAS-II and 5 – 9 will be the same as those that would have been asked if the exam had remained a paper and pencil exam; in other words, the questions will be similar in format and style to previous offerings of the same exam.

I have searched but I was unable to find any update on this question in regards to Spring 2021 exams. Does this mean we should be prepared for more sophisticated questions using larger datasets during the Spring 2021 Exam 7 sitting? Or will this sitting still be using the same question style as those that would have been asked if the exam had remained a paper and pencil exam?
