<p>I am self studying AP Environmental Science this year. I have Smart Pant's Guide, PR APES Guide, and 500 APES questions, but that is it. Is there any textbook I could potentially use that could help me get a 5? If I did have a textbook, how would I know what to study? Do I study ALL the chapters or is there specific ones? </p>
<p>Thanks in advance! </p>
<p>P.S. If you know of any links where there are released exams or FRQs, could you please tell me!</p>
