yeah like the first 15-20 questions were pretty easy though i may have gotten like 2 of those wrong, then from there it got pretty hard

MMHS i calculated my score yesterday, i should receive 90-100 marks. should be enough for a distinction/high distinction (based on past experiences)

    is distinction/high distinction based of everyone who tries or the school

    i may/may not get highest in school

    most likely will, like a 80% chance but kids used chatgpt so idk lol

      which is just bs

      Can somebody explain the grapefruit and orange question to me?

        Chessisthebest so basically, the farmer took 120 grapefruits and x oranges. 1/10 (10%) of grapefruits look like oranges and 1/10 (10%) of oranges look like grapefruit. also 1/5 (20%) of all fruit looks like grapefruit (this incl. 90% of grapefruit - i.e. 108 grapefruits and x/10 oranges.) if we make an equation, we should have x+120/5 = x/10 + 108. if you solve this equation, you should get the answer of 840.

          bitter i finished all the questions except 27, 29 and 30.

          So i only realised a few hours after doing the amc that i messed uo the rectangle and rod questions cuz i’m quite sure that the rectangle one was 674 and the rods questions was 146.

          Btw was the one about fruits question 27 or 28?

          my whole year was forced to do it... actually hell im not good enough at maths for this 😭

            wow now that i realise, i just needed to read the question properly for the oranges one because i could've easily done it but whatever, i was confident with like 85-90% of the test apart from like the last 5 questions
