New edition of a book?

Hey freshies!

When I was in my first year I FREAKED out when I was able to buy, let's say the second edition of a book, but the syllabus of the new subjects asked us to buy the third edition. Relatable?

Often the newer edition of a book is a lot more expensive than older versions, and often times also not availiable second hand - thus has a massive impact on your bankaccount.

Over the years I realized that newer versions of books contain often times just minor adjustments or a change of order of chapters. Therefore, in most cases the older version of a book is JUST FINE! However, talk to your professors about it and check if you find the new version on amazon (or similar) and compare the table of contents.
