An updated version of my revision video for Paper 1 of AQA GCSE Biology (9-1) (8461 specification) covering:

0:30 - Unit 1 (Cell Biology)
22:12 - Unit 2 (Organisation)
37:17 - Unit 3 (Infection and response)
50:51 - Unit 4 (Bioenergetics)

If you are taking AQA Combined Science (8464 specification) then you should skip:
2:48 - 6:34 Binary fission, culturing bacteria and zones of inhibition
46:15 - 50:51 Monoclonal antibodies and plant disease
As these topics are only for those taking the "triple science" exams

These sections are clearly marked with bright pink headings at the top of each slide.
