I just had a look at your retry questions. I presume you are talking about the cloze type questions where you have to say which word can go in the place of a certain letter.

It doesn’t matter that the questions are not in alphabetical order because everything you need is contained in each question. If you scroll to the end of the text, it tells you which letter you should be replacing.
e.g. ‘Which word replaces [G] in the passage’
