    1 keep an eye on time
    2 make sure find all the solutions
    3 don't miss any question
    4 try drawing a graph when cannot solve problem sometimes e.g. Asked to find range of y
    5 make sure answer is in the range. -90~90
    6 be careful when substitute any value I.e. t or x..
    7 don't think about how many marks u will get when sitting the exam it's a waste of time

    Good Luck guys

    And two tips I would give would be: When finding an equation, make sure to watch out if they want a tangent or normal!
    And, when differentiating make sure that if it comes up as dx/dy you convert it to dy/dx

    That's the differential of a^x, the differential of x^x is x^x(ln(x) + 1), although I didn't know we needed to know it for c3

    Hey guys, one teensy tiny question I'm still unsure about: are mod graphs that give you only one domain always symmetrical about an axis?
    Thanks.

    Best of luck!

    If a function has a mod around the whole thing it is symmetrical on the x-axis, if the mod is just round the x term it is symmetrical on the y-axis

    Does this answer it?

    A good one is to take a deep breath in, hold it for five seconds, then slowly exhale. Do this a few times
