I said this in another theard...
Solve one past paper,then see the mark scheme of it.
And you'll know how to solve rest of the paper.
Solve past papers from 2009 till 2013.
As well as check the Result Plus of the papers you have solved,it helps too.

And what about references and bibliography and all? does it have a fixed format?
it kinda does. You have to know how to arrange a reference or bibliography :

Magazine & Newspaper Articles

Format:
Author's last name, first initial. (Publication date). Article title. Periodical title, volume number(issue number if available), inclusive pages.

Note: Do not enclose the title in quotation marks. Put a period after the title. If a periodical includes a volume number, italicize it and then give the page range (in regular type) without "pp." If the periodical does not use volume numbers, as in newspapers, use p. or pp. for page numbers.
Note: Unlike other periodicals, p. or pp. precedes page numbers for a newspaper reference in APA style.

Examples:
Harlow, H. F. (1983). Fundamentals for preparing psychology journal articles. Journal of Comparative and Physiological Psychology, 55, 893-896.
Henry, W. A., III. (1990, April 9). Making the grade in today's schools. Time, 135, 28-31.

Online document:

Note: When citing Internet sources, refer to the specific website document. If a document is undated, use "n.d." (for no date) immediately after the document title. Break a lengthy URL that goes to another line after a slash or before a period. Continually check your references to online documents. There is no period following a URL.
Note: If you cannot find some of this information, cite what is available.

yeah. i'm guessing a question related to bibliography came in 2011, so check that year. Overall, don't be scared or stressed out, its a paper which needs processing and thinking. i recommend getting sleep before the exam :) do you start on the 7th? :O

HELP! what does it mean to say ''SD values overlap''????
it means standard deviations overlap. when they overlap, the data is said to be less reliable. Say you had SD's of 4 and 6 those overlap (PS: they can never go that high) the data is not reliable, even if SD's are given
