Firstly, you should not use the notes on their own – they are lecture notes and should only be used with the lectures. In the lectures we explain and expand on the notes and work through all of the examples. If you are not watching the lectures for any reason then you must buy a Study Text from one of the ACCA approved publishers and study from that if you want to have any chance of pass the exam.
Secondly, if you look at the contents page of the lecture notes then you will see where to find printed answers to the examples!
