I notice in the familiarisation there are no mixed up sentances. We have just done some on a Bond practice and I can't see how they lend themselves to multiple choice.
DS3 is fine with them, so would be great if they are in the test, however he has dysgraphia so his writing can often be difficult to read not helped by how he now writes some letters in the French way. As it is we are still trying to iron out his french v british numerials
The mixed up sentences are adapted to multiple choice by adding an extra word that needs to be removed. So you'd need to mentally rearrange the words in the sentence, find the superfluous word and select that word from the multiple choice.
