Available for sale investment

first, is available for sale investment and non-current asset held for sale is the same thing?

i found it confusing looking at the examiner’s suggested answers for Exams in December 2009 and June 2013.

as in December 2009, in statement of financial position they classified the “available-for-sale investment” as a non current asset.

while in June 2013, they classified the “Non-current asset held for sale” as seperate from Non-current asset and Current asset. – i mean like they sum up all non-current asset, then sum up all current asset then they add the total NCA and CA to the Non-current asset held for sale to arrive at the total asset figure.

are both methods are corrent? will i lose marks by doing so? thank you in advance
