GCSE chemistry help?? I don't know which reactivity series is the right one lol

So I was trying to revise the order of the reactivity series but when I searched it up there was so many different versions, especially these two:
Potassium
Sodium
Lithium
Calcium
Magnesium
Aluminium
Carbon
Zinc
Iron
Copper
Silver
Gold
OR
Potassium
Sodium
Calcium
Magnesium
Aluminium
Carbon
Zinc
Iron
Tin
Lead
Hydrogen
Copper
Silver
Gold
Platinum
I've noticed the second one despite being longer, doesn't have lithium in it, and it also has a bunch of elements the first one doesnt ;-; Does anyone know which one is the right one to use, for gcse chemistry? Or is it meant to be a completely different one to use 😂 (I'm doing Edexcel and Combined but I doubt that should make any difference)
THANK YOUU
