I’m currently taking AP Bio and am just wondering what to brace for as we go. Could someone who has taken the class say what were generally agreed to be the most challenging versus easiest sections? (So far we’ve done signalling, membrane, respiration, photosynthesis, and the cell organelles, I think. Now we’re starting cell division)
I found it all to be quite easy, to be honest.
Personally, I think it depends on how interested you are in the each unit – the more interested you are, the more in sticks with you on the AP test (at least for me). I wasn’t very interested in cellular respiration and photosynthesis, but I really liked the immune system, viruses, DNA replication, plant phototropism, evolution, and all of ecology.
I can’t really speak for the rest of my class … there were 76 of us.
I actually really enjoyed the AP exam 
It’s not a memorization test, it’s applying what you know.
Sorry … this wasn’t a very helpful reply.
What book are you using?
My teacher (I’m in AP Bio this year) told my class the hardest unit is cellular respiration, because of glycolysis and the Krebs cycle.
@LaikaDoodles well the teacher mandated cliffnotes (which I find for an initial overview too opaque) and I WAS using the princeton review because it’s amazing for chemistry… until it tried to tell me the three types of bonds are ionic, covalent, and hydrogen.
I assume you’re using the Campbell Biology textbook?
Yeah
