A) Save your programs. It will keep you more organized as you work through the exam and is well worth your time. What happens if you accidentally close the UI and you lose your work? Far better to take a moment to save the program as explained in the exam instructions. It won't directly affect your score but could have a huge indirect impact if you don't. (Also, for clarity, on the A00-232 Advanced Programming exam, you must save your programs to get credit for your work.)
B) Stay away from questions you found on the Internet, regardless of their age. Many are wrong or will waste your time when they aren't connected to the current A00-231 exam content guide. Also, note the SAS Certification integrity expectations and candidate agreement. Note the section on Non-Independent Test Taking and gaining pre-knowledge of exam questions, particularly:
Pre-knowledge refers to the use of study materials containing questions from the actual certification exam. Anyone who uses actual certification test questions (obtained by any means, intentional or not) to prepare for an exam, compromises their ability to test independently.
As @Anne_A pointed out, SAS provides full length practice exam for free for you to check your preparation ahead of your exam.
