Do you get no marks in a maths "show that" question if your method is different?

...to the one in the markscheme? Even if it's totally valid? because I'm looking at markschemes and they dont say anything about alternate methods, even if they are completely valid.

No in the real exam the examiner will have a more detailed mark scheme that includes all of the possible alternative methods. The mark scheme you have will show the most common ones. If your method is valid and you have shown enough detail in your working, you will get the marks.

Unless they've specified a method, you'll get full marks as long as your method that you've shown is correct.

sometimes if the method is obscure, handwriting and structure is bad you might get nothing.

Something like this usually can be challenged in a re-mark (if you suspect it took place)

What if, say somebody used the product rule to differentiate the product of two functions of x in C1/2 instead of expanding then differentiating.
Would one get full marks?
I struggle to understand mark schemes lol- don't know how strict they are.
is it literally any correct method generally gets the mark unless they want you to use a certain method?
thx

Unless it tells you which method to use and your method is correct and clear then yes, you'd get the marks. If the mark scheme expands it first though, it may be the easier way.

The mark scheme we have is the same as the one that is published (although it is normal to annotate it based on discussions at the initial meeting and subsequently).

You are correct to say any valid method should be credited (unless a method is specified in the question).
