Hi!
I’m taking two AP courses this year: AP Bio and AP Lang and Comp. Today was my first day of school and my bio teacher has suggested that we buy Barrons. How are the flash cards? Are they worth the purchase? Also, I asked my AP Lang and Comp teacher if we need AP books/what AP books he recommends students to use on their own time and he didn’t really give an answer like he said it’s not really worth it but I can try Barrons (because I mentioned Barrons in my question). What AP book is good for AP Lang and Comp? If you would like, include how you used it (like studying schedule) and your final score! I would like to know 
Thanks!
