Also, is the marking similar to maths where they would read crossed out answers? Seems i got close to one of the calculations but I accidentally crossed it out :<

Did you guys do a linear line of best fit or a curve?

Just hand in a note after your exam or on Friday, then ask the office/principle about it.

Yep. The concentrations found are halved anyway using c = n/v AFAIK they don't test for every dot point, as in 2015 there were no AAS questions. off-topic: for some reason, a study guide said to divide the indicies by the volume i.e. if its like 2A + B <-> C + D with 10 L, It would be like...

Just do 4U Math. 5 Subjects galore :P.

OP's profile is also filled with stream sites.

in the past papers have you generally seen a curved line of best fit like 2015? haven't had time to do that many PP's.

I thought thermal cracking was more effective for alkanes which are longer than 25C? However it's probably more expensive due to the amount/cost of energy for the high temps. Ahmad Shah:  This [Catalytic Cracking] process uses less heat than THERMAL cracking, but it cannot decompose large...

idk i've heard they had some kind of application/website which they can check work to see if its exactly the same writing styles could also be identified

Actually, if I recall correctly, I've gotten marked down for connecting the dots rather than a line of best fit in a line graph -.-

its interesting since the marking guidelines specify "a line of best fit". Where as I'm not sure that's a line of best fit at all. I would've thought the line graph would just be adjacent connecting the dots too, but am always hearing about how that's frowned upon, and it has to be a line of...

I'm still confused on how markers want us to do a line of best fit. 2015's Q22a) has dots all over the place. The MG shows its just a smoothed out connect the dots line. Any ideas on how it should be generally done?

tfw now i think i'd rather study math than chemistry

Aren't soaps insoluble in hard water? I asked my teacher and he said its especially important in country areas where mining is prevalent, or essentially there's alot of hard water

Were your disadvantages ever less than 6 months?

-4 so far in MC rip

Exam is already up on a certain rival's site.

Circled casual then crossed it out. Thought 66 year old was more expensive due to inefficiencies and needs for benefits. Pregnancy one was so bait I fell for it. I circled EEO but it's Sex Discrimination.

Actually my issue was that it was less than 6 months. EAS specifically says long-term, but I'm wondering if it's possible to still get bonus points, especially since it was doing my trials - a significant portion of my HSC.
