I posted a link earlier and I just realised that those who don't have an account won't be able to access it so I'm going to attach the notes here. Although it would be advisable to sign up for that site cause it has very helpful notes!!
http://getrevising.co.uk/resources/edexcel_biology_unit_2_notesOh! And the attached notes are in parts so follow the number order! It's a continuous file but I had to break it down cause it was too big to upload altogether. Follow the numbers for it to make sense and part 5 is split into two cause it was too big still :P
I DON'T OWN THE NOTES AND I DIDN;T WRITE THEM!
Hope they helped and if they don't open or something just tell me and I can email it to you. Send me your address in my inbox though! There was also an audio of the notes that was too big to upload here so if you want it and learn better by listening send me your email in my inbox! ONLY MY INBOX please cause if it's on here I won't bother to sift through pages to find it :/ I'm too lazy. If you do inbox me specify what you would like okay? Once again I don't own the notes and I didn't make them
Seriously hope this helps!!
