How to read Mark scheme

I was looking at one of the Maths Mark scheme (M1), there's one mark allowed for "ft c's values" what does that mean? "cao", "ft x, y" , "dim correct" , "si" and "R1", those abbreviations are too hard to understand........can anyone help me out please

ft c's values - Follow through candidate's values

CAO - Correct Answer Only

ft x, y - follow through values of x and y

Don't know about R1 - A1, B1, M1 and E1 are different types of marks

A: answer
B/R: reason (statement) (I believe)
M: method

cao: correct answer only
ft: follow through (to avoid unnecessarily penalising candidate for going wrong at the start of the question)
oe: or equivalent (e.g. 0.3333... = 1/3)

Not sure about dim. correct but si is 'seen or implied' i.e. as long as you're doing the right thing you'll get the marks even if you don't explicitely say it.

What about "avp" in biology mark schemes?

Within WJEC mathematics they only use "dim correct" in mechanics, where you need to use vectors. (forces, moments). I believe this is the mark for having all vectors pointing in the right direction on the drawing.
