When I studied BioMed, I boguht new textbooks every semester.

Nk no wait let me rephrase that. We had different texts prescribed for different subjects. After the first semester I bought second hand and older editions. Where I could, most of those texts became obsolete if they had newer editions, the way things move so quick in science.

For my education degree I am buying new because they aren't as expensive and they will hopefully last me.
