AP Bio at a first glance might seem to be all about memorization and knowing the vocabulary for each unit, but it is actually more than that. Biology is also about gaining an understanding of what comprises the building blocks of life and the processes associated with it from cellular respiration to DNA translation into RNA. By knowing the key points to focus on, however, you'll surely snatch that 5 and learn to appreciate the class as a whole.

🧪 Unit 1: Chemistry of Life

🔥 Quick Tip: Identify what makes each of the four groups of macromolecules similar or different from each other. This will help you understand later concepts such as the plasma membrane and DNA!

🧬 Unit 2: Cell Structure and Function 

🔥 Quick Tip: Familiarize yourself with the function of most, if not all, cell organelles by using analogies to real-life scenarios and mnemonic devices!
2.3 - Cell Size
2.9 - Mechanisms of Transport

🔋 Unit 3: Cellular Energetics

🔥 Quick Tip: Use flashcards to highlight the major steps of cellular respiration and photosynthesis, the key players involved, and the byproducts of each process. It's easy to confuse NADPH with NADP+!
3.7 - Fitness

🦠️ Unit 4: Cell Communication and Cell Cycle

🔥 Quick Tip: Remember the acronym PMAT for the order of events of mitosis when it comes to the cell cycle and be sure to be able to name key events in each phase. Signal transduction and cell communication provide additional background on the technicalities behind various intracellular processes that could be asked on the exam.
4.5 - Feedback
4.6 - Cell Cycle

👪 Unit 5: Heredity

🔥 Quick Tip: Practice your Punnett Squares and do lots of practice problems! Many students make careless mistakes because they gloss over them due to its seemingly easy-to-set-up nature.
5.1 - Meiosis

👻 Unit 6: Gene Expression and Regulation

🔥 Quick Tip: Do a quick refresher on the differences between DNA and RNA before making flashcards for the steps of DNA replication, transcription, and translation. Don't confuse those three processes with each other!
6.0 - Overview of Unit 6
6.7 - Mutations
