I am not sure what you mean by ‘structured’ – I guess you mean the MTQ’s in Section B of the exam.
There are tests at the end of each chapter – these are MCQ’s as in Section A. In addition there is a link to a mock exam from the main Paper F2 page, which has both Section A and Section B type questions.
However, as we make clear, you must get hold of a Revision/Exam Kit from one of the approved publishers. They contain lots of exam standard questions to practice on.
