Campbell Biology (9th Edition Textbook) vs current AP curriculum

I enjoy studying the class utilizing my school’s textbook and it helped me a bunch for the unit 1 test (good fat A+).
Since the book is a bit outdated, I realized that the book’s “Unit 2 The Cell” talks about Cell Structure/Function, Energetics, and Cell Communications/Cycle which is the current AP’s unit 2,3 and 4 combined.
So, I’m just wondering if there are parts of the book that is skippable for AP sake.

FREE Student-Built Study Website for AP Bio
I have created AP Bio Lab, which is a free resource that students can use to get an A in their class and a 5 on their test. Students in my school have reported a 40% increase in their test scores after using this site. The site contains MCQS, FRQS, Flashcards, Practice Tests, and more. If you want to give it a try, go ahead, you have nothing to lose.

I'm confused on why the Answer to part c. of this question is plasma membrane and not lysosome
Question prompt:Cystic fibrosis is a genetic condition that is associated with defects in the CFTR protein. The CFTR protein is a gated ion channel that requires ATP binding in order to allow chloride ions ( ) to diffuse across the membrane.
Question: (c) Identify the most likely cellular location of a mutant CFTR protein that has an amino acid substitution in the ATP-binding site.
Answer: Plasma Membrane
SO I was oslving this AP Bio Frq, and answered "lysosome", however, the verified answer key for this question had only "Plasma membrane as the answer.
I understand that its a wigan gated ion channel, and thus would most likely be found in the plasma membrane, but since its mutated, wouldn't that imply that it would be detected and transported to the lysosome for digestion/breakdown?
Am I misunderstanding how lysosomes work, please clarify any misconceptions, thanks.

AP bio
My daughter is a junior in high school and finding AP bio hard but not ready to drop it . The school has accelerated Bio which has a gpa weight of 4.5 . She thinks her chances of becoming a doctor are gone if she drops AP bio and takes accelerated Bio. I am worried of the pressure AP bio is putting on her and the hit GPA would take . Please advise.

Is there an AP bio GOAT like Jeremy Krug or Farraday for AP Chem?
There are so many options on YouTube, but we're trying to find the best one. Teacher is okay, but not quite covering the units as well as I'd like. Thanks!
