Biology marching scheme Edexcel

In IAL edexcel biology marking scheme I have seen a quotation saying "correct answer with no working (2 marks) " what does this mean ?

Without any context, it would appear to mean that if you provide the correct answer, but provide no evidence of any calculations to demonstrate how you achieved that answer, then you will be awarded two marks.

The general rule in mathematical or calculated answers is that if you obtain the correct answer, then you are awarded all the available marks. The exception would be that if the question has said to use a particular method or approach, then you would need to show that you have used that method or approach by writing down each calculation you used to obtain the answer.

Do you have a link to the mark scheme to which you're referring, and the number of the question involved?

If I wrote the answer with the method, and if the method I followed is *wrong*, will I loose my marks?
