My son took the paper PSAT 8/9 in April and scored in 99th percentile with no advance preparation or exposure to the exam. That score fits with paper standardized testing he's done throughout schooling showing high percentiles across the board over the years.

He moved schools and was made to take the digital PSAT 8/9 in October (6 months later) and his score dropped into the 70th percentile range. He has ADHD and computers have always been a distraction/interest (during zoom home schooling with COVID he was constantly focused on optimizing computer performance instead of focusing on content of lessons). Now standardized testing will all be on the computer. Do you have advice on how we can help him prepare for future standardized test so that he can focus on the exam itself and show that he knows the material and can do well?

We are not interested in accommodations (modifications to how he takes the test), but advice on how to develop skills to be able to take the exam digitally.

Thank you!
