Can you please list or state what book/s you have found irreplaceable during your time studying the degree? I have found that during my undergrad degree I fell into the trap of buying some books, which I did not need in the long run...I only stuck to one book and spent the rest of my time referencing articles.
It would be most helpful e.g. if one or two books are recommended by students at different unis then I would be more inclined to invest in them.
Thanking you in advance!
Why do people do it?
