<p>I'm currently using cliff's prep book for bio and have been taking notes as I go along but it's getting really tedious as biology is pretty descriptive science at this level. how do you guys use prep books? just read and do the probs or would recommend taking notes? also, would we need to know the exact molecular structure down to each atom of things like nitrogenous bases, glucose and sugars, ATP's, and other weird complicated molecules ?</p>
