    How likely is it that another 18 marker will come this monday exam?
    Very unlikely.

    However, if you look at may of the last parts of section A, it typically is actually 18 marks but is split up into an 8 mark part a) and a 10 mark part b) (sometimes vice versa)

    In ICT do not be intimidated by something such as an 18 mark question as the marks are veryeasy to pick up as illustrated by the home entertainment question. (remember to deduct two marks for the QWC to make it even less intimidating).

    By doing your past papers the questions become transparent, the most important part is understanding where the marks actually come from. Every time home entertainment comes up, its basically the same question again and again, except sometimes they want you to arrange it in a certain way ie: reserving health concern disadvantages of home entertainment for the part b) etc...

    With that said, don't worry if a massive question like that appears as the marks are awarded in a totally different way than in say, English literature or business etc... where you must work your a** off for the marks. Very little analysis or thought required in ICT, just a case of learning the markschemes and trotting out what you remember in the exam, which is exactly why this qualification is being scrapped as it is so impractical.
