Our teenager made a rather valid point which might not apply to SAS as she took the IB Diploma exam last year. She said that friends who were in another IB school last year who used their laptops in class for most written assignments as well as research found writing for two hours a torture. Their hands cramped up and precious time was wasted to rest their poor hands. I am not sure how much writing AP exams require and if students (other than those with dyslexia) may use their laptops to write their exams.

No surprise to me that some kids found hand-writing can be painful after they get used to use computer to do all the written assignments.
AP exams require all in writing as well.
