Anyone know if not putting units would lose a mark? realised throughout the test i hadn't put any units, such as the time of concentration, or the km/h rate thing? also, if i had t=something (which was long and untidied, but right) and put that in my calculator incorrectly to get a wrong simplified answer, that would lose a mark or two right?

The markers are usually fussy about the units in 2 unit, but not so much in 3 and 4 unit. So, no, i doubt they'll take of marks for not specifying the units

if i wrote x=1 and x=3 for the inverse question instead of the points (1,1) and (3,3) will i lose marks?
and for the binomials. i wrote it is a multiple of 4 and n>0 but i didnt include 0 so will i lose that mark as well?

yep, you lose marks man. bad luck.
But this test was basically about eliminating silly mistakes such as this. as someone above said, thats what separates a 70/70 and 65

Stop worrying people, u still get some mark if you show some steps of your working out, and they also carry on your mistake, so you'll be fine

No you won't get the mark- its a one mark question so if you get it wrong, you get it wrong lol. And 50/70 will probs be a tiny bit below 90, but I'm not really sure tbh- sorry

I barely averaged 45% (no weighting) and got 39/50 in the exam very happy and opened up many opportunities more easily. That said the exact was very easy i was very tired coming in to the exam and did the third part thinking it was a the second and lost like like 10 minutes. Man just wondering what could had been haha. Very late i just got around to doing this =)
