Yes, subject to…..do not simply ‘consult’ the lecture notes – you need to print them out and have them in front of you while you watch the lectures. Also, not only must you buy a current edition of a Revision Kit, but you must attempt every question in it (and don’t look at the answer until you have attempted the question – then you can learn from your mistakes).
Otherwise that is enough – the lectures are a complete free course and cover everything needed to be able to pass the exam well (provided that you also practice the questions in the Revision Kit).
Any problems, then ask in the Ask the Tutor Forum and I will help you.
