A level psychology biology and chemistry notes??

Hey,
I have finished my gcses and starting a levels in September and I am taking biology (edexcel B), chemistry (edexcel) and psychology (aqa).
This is a big ask but does anyone have notes for any of these specific subjects preferably the first unit or whatever?? Purely because I am going on holiday for the rest of the summer and I think it would be helpful to read before starting in September!

Thank you so much !

I can only help with psychology but these books are all you need to pass the course:

Shop around as they can range from £15 to £30 but your college will likely have some to borrow or buy (ours offered to buy them back at the end of the year as well but I kept mine).
