I don't really agree with your last statement. It might be a cultural thing, I have no idea where you went to school, but what do I care what grades other students get? If you are on the verge of failing on a test, then yes, the average of the group will determine whether there will be corrections made to all grades which could make the difference between passing or failing (5.3/10 becomes 5.6/10), but apart from that I could not have cared less when I was in school or university.

You are right that pen and paper was complex enough. In fact there are many studies that show that children learn better when writing on and reading from paper than on and from screens. In picking schools for my kids I will take the use of paper and real books into very strong account.
