A testing center might tell you that you're going to get paper and pencil but on the day of the test, they'll give you laminated paper with marker.
It happens plenty of times. Also, on the test day, you might see others using scratch paper and you're stuck with laminated paper and marker.
It sucks but you have to live with it. Just practice with marker and laminated paper. That's all you can do.
In reality, the laminated paper/marker isn't so bad except for during the math section.
