Note from MADS MADLAD:

Thank you for buying my summary. When I was writing these I sometimes
struggled with this program, but there were no summaries available. This is
why I decided to write something that is truly complete with a lot of effort put
into it.
It helped me and my friends get good grades, but I always had you in mind, the
future reader. When necessary, I always went the extra mile to make my
summaries, more readable, organized and complete.
If you feel like it, leave me a review of how the course is going using this
summary, it will make my day to hear your feedback.
