TEAS exam started with Science instead of Reading?

I took my ATI TEAS exam today at a PSI testing center, and my first section was Science. Reading was actually the last section I completed.

I thought the standard order was Reading → Math → Science → English, so I was really surprised. By the time I got to Reading, I was already mentally exhausted and I feel like it affected my score.

Has this happened to anyone else? Is it normal for PSI to change the order of the TEAS sections?
