I think 'reading in class backed up by reading at home' is what most of us are advocating, actually.
You read, analyse, & write critically on pivotal scenes in class & leave the bits that you don't have time for to independent reading.
Not everybody will do the independent reading, being pragmatic about it, & plenty more will dutifully read those bits without actually understanding more than the plot, but given some judicious summarising in class they can still have a crack at the exam - which is lucky as for some bonkers reason it's going to be untiered.
Having spent a half term last year racing five of my year 10 boys through 'Game of Thrones', I'm not for a minute counselling despair on the home reading; many kids can & will get stuck in. But lots can't or won't, & you just have to plan accordingly.
