sorry if this is in the wrong forum this is my first time making a post on here
which editions of Campbell Biology would be best for USABO 2018?
i have been using the 9th edition online, the only one i own irl currently is the 4th edition. would this be okay to also use?
It would probably be better to stick to something 8th edition or above. It doesn’t need to be brand new, but the 4th would be missing enough material to mess you up. DM me for a pdf of the 11th if you want. If you have any other questions post to this thread: http://talk.collegeconfidential.com/high-school-life/1997342-usabo-2017-2018-p5.html
Heydo you think you can send me that PDF.?
