Ap bio self study

I recently started studying for ap biology from the Barrons book. I have finished 6 out of 19 chapters and plan on finishing the rest before May. Although I find the course moderate and not too hard to self study for, everyone has been telling me that it’s too much information to finish before May and that I will not be able to process that much information. So do you think that I have too little time? Like I even made a schedule and if I finished 3 pages a day I’d finish the whole book, but is ap Barrons and only ap Barrons a reliable source… I can’t really buy any other books and shipping where I live takes too long

Take some practice tests after you study the book. Barron’s is good in that it over-prepares you for the exam. You should have enough time if you are willing to put effort into processing and memorizing the important information.
