<p>My question is for AP Envi must i memorize the geological time scale and the different eras and periods.</p>
<p>no. just know some general stuff ( pre -cambrian, then cambrian is first ones, jurassic and the other two are dinosaurs that’s about it)</p>
<p>no you really don’t need to know that at all. barron’s will so overprepare you for the ap, and pr will underprepare you so what i did was get pr and barrons flashcards. still waiting on the score but im almost positive of a 5.</p>
