These are always undergoing fine tuning, so be sure to download and study them afresh, right before the exams. There are purple slides in many of these; purple slides have material which is more advanced or supplementary, not material from which I make exam questions. Also, pay special attention to the RED SLIDE (key points) that ends each PowerPoint. These too are very important for studying for exams.
