Note that these slides are reminders to me as to what topics I should cover: you are expected to read around the subject. Don't treat the slides as the entirety of your study.
The file numbers don't correspond to anything in particular in terms of lectures or subject covered.
I may have skipped some material in lectures: why not improve your general education and read the extra too! The exam will only be set on material covered in lectures and your lecture notes will tell you what was covered in lectures.
