AQA vs OCR A Level Chemistry practicals

Can I use MaChemGuy's videos on the practicals to revise for the AQA practicals or are they really different?

I would say you can, as they may describe some practical techniques in depth.

But be aware that AQA may assess different practicals to OCR, or otherwise use different procedures, so I would check the AQA practical notes/guide (if there is one) to familiarise yourself with the procedures you need to be aware of and use any MaChemGuy videos that explain essentially the same procedure.

Thank you ! If you did Biology how did you revise them please?
