Absurd Click Bait
The Daily Mail claimed that this grammar test is so hard no one will get more than 10 or 20 right. That is absurd, I nailed them all (yes, I have lots of grammatical mistakes in this blog because I am a sucky and indifferent proof-reader, not because I don't know what's correct).
That has to be just click bait or some sort of self-esteem reinforcement process. The only other explanation is that there really has been a divergence between going to school/college and education.
