I have cleared SAS A00-231 exam and special thanks to Analytics exam. Practice tests helped me to prepare well for actual exam. Please note in the actual exam you'll have 50-60% practice based questions which are not multiple choice questions and if you prepare from SAS 9.4 Book and practice with Analytics exam practice test you'll definitely clear. You'll find questions from SAS 9.4 book in the Analytics exam practice tests.
All the Best!!
