  • LOL oh physics......is getting to everybody. Biology would be my preference of science.
    I don't......think anybody is going to notice you. It's a tutoring centre, there's going to be lots of people around anyway.
    Hey Spi,
    The things in preliminary that you need to understand are examples of the 7 information processes in an information system & the information system in context diagram. You also need to be able to apply these to scenarios too.
    Social & Ethical issues are always asked & are easy marks.
    If you're doing the option topic 'Multimedia Systems' then you may want to revise 'Roles of people involved in systems development'

    Understand the context & DFD diagrams as you may be asked to draw one.

    Know the difference between participants & users. I think this is the thing that a lot of people stuff up with in exams.

    Good luck!
    how about this question...
    if A and B are acute angles with sin A=3/5 and sin B=1/2,evaluate:
    (i) sin(A+B)
    (ii) cos(A-B)

    answer to:
    (i) is (3root3 + 4)/10 and
    (ii) is (4root3 + 3)/10
    haha, i just started learning the year 12 physics today, so so so many formulas! there are like 10 billion of them.
    aw. i haven't done that . that was one of the few reasons why i did not leave, all the other tutors are ahead.
