I mean to ask that if we do NOT write the examiners answer (i.e points covered in examiner answer) and instead write the answer given in studytext (points covered in studytext) then would we able to obtain full 3 marks for DGM or not if we have written entirely different points than points written in examiners answer, but provided these points are written in studytext?

Sir basically I mean to ask that for theory parts in F9 in sec C of paper If we do NOT write those points in our answer which are given by examiner answers, and instead write those points in our answer which are not given in examiners answer but these are written in Bpp/kap studytext , then would we be able to get full marks in theory parts OR is it more better to write those points in our answer which are given in examiners answer in order to obtain full marks for theory parts of section C of paper?

I have answer you on this already. The marks are for proving you understand - you do not have to write exactly what the examiner writes, or exactly what is written in your study text. If what you write is sensible and is answering the question, then you get the marks.
