- I practiced in Pearson environment for a few weeks. I was aware of almost all the limitations. Instead of doing problems in Excel, I would just open the Pearson testing environment up and practice there. I finished exam 9 with 45 minutes left. For me the extra time didn’t help because well quite frankly the test was extremely hard. There were four or five questions that probably will make it or break it.
I emailed the CAS about all the issues in the environment and they didn’t tell people. They were aware of them. For example, typing an incorrect formula makes the cell revert back to what was in it previously. So if it was empty it remains empty. If it had a different value or formula it goes back to that one.
