Question Regarding the IGCSE Edexcel Specification

G'day,
So I looked up the IGCSE Edexcel specification for Physics and it is dated to June of last year. The reason the spec is important is so that I can cut down my studying time for Physics by looking at what will come in paper 1 and paper only.
Just want to know if the information for the 2013 specification will be still relevant for this year.
Thanks!

their is two routes the seperate sciences or the combined, which are you doing?

I'm pretty sure I'm doing the separate ones.
Chem, Bio and Physics have both a Paper 1 and 2. 120 marks paper + 60 marks paper.

then I'd suggest you revise both papers, but the specification hasn't changed.

So your saying there is a possibility of Edexcel completely disregarding the topic allocations for each paper?

No. I meant that their isn't a possibility.
