  2. Thank you so much for this. Also using the summaries you provided to make flash cards. If i get a 9 its thanks to you.

  3. How do mineral ions leave the proxima tubule to be reabsorbed into the blood, is this through diffusion? And also water coming through the permeable walls of the collecting duct (dependant on ADH), is this through osmosis?

  4. I literally love you!! got like three weeks before my exam and this is SAVING me x thank you

  5. this helped me a lot as i'm homeschooled theres not much help out there as far as i know of so thank you so much 🙂 <3

  6. Thank you so much for these vidoes, they are amazing and perfect for revision as I have my GCSEs next week!!

  7. if anyone's still up/is awake and is stressed about their Bio exam: GOOD LUCK!
    (also thanks to Hazel for making this video! :D)

  8. I’m seriously watching this at 9am THE morning of my exam I know nothing let’s help this hopes 🤞

  9. Watched this, made notes and felt fully prepared, only for edexcel to ask me about rat sperm and salmon. Wasted 2.5 hours of my life watching this but not as much as the 3+ years learning a spec that only contributed to 2% of the fucking paper

  10. If you're watching for paper 2 biology tomorrow, good luck! Watch on 1.5 speed and subtitles! Thanks Hazel 🙂

  11. i have my bio paper 2 exam tomorrow. will it be enough to ONLY study the "biology only" parts, or should I study paper 1 syllabus as well? will questions from paper 1's syllabus come in paper 2?

  12. CGP Book: “Auxins are Plant Growth Hormones”

    Paper 1: “Suggest why auxins are not hormones”
