This wonderful stuff, Jesse. A quick question.. With the pseudo-ternary graph example, was that final pink line relating to the "left-over", 0.2, portion of class 3 meant to begin at the bottom side of the triangle? Because you drew it coming from left-hand side, or class 1, which seemed to be exclusively for the 0.6 portion... And just to be clear, for it to be a possible compound, all three lines must intersect at the same point, correct? (as per compound A). Thank you, sir! Look forward to more of the good stuff.
Hey there! Ooh good catch, I did go the wrong way on the pink lines. I should have gone horizontally for class 1 at 0.6 Yeah his should give a compound at the position just above and to the right of point A. Lining up with class 1 = 0.6, class 2=0.2 and class 3 = 0.2 And yep, they need to all intersect on the one point. You’ll find that no matter which point you look at on a ternary chart, the three axes will add up to 100% (so long as you’re not doing what I did and read the axes the wrong way! 😅)
@@jesseosbourne if it is question based it would be so good. I have a bit knowledge about logs but finding it difficult to apply to the questions. Thank you in advance.
36:48 haha I caught this too, both times I commented then realised that someone else picked up on it - PS AMAZING content I remember lots of graphs that fed into each other. You had to find a point on one graph then use it on another graph. Time consuming.
I actually admire that you’re able to post content that has some errors in it. It means that you’re able to put out more content in the same amount of time and the errors don’t take away from the message you’re delivering. I often battle with perfectionism that interferes with my ability to complete tasks.
When I did the Gamsat recently,, and there was a difficult graph style for one of the units. From memory it had 3 axis, was angled, so potentially 3D, was about Oxygen levels (two other variables I don't remember) of birds and lizards or something. I found it incredibly difficult to interpret. Did you come across graphs that had 3 axis? Or advice on how to read graphs that are unfamiliar?
Hmm that sounds familiar to something I got in March, actually. I'd have to see the graph in front of me to give any good advice here but can probably do some more graph oriented question in the Sample Questions Walkthrough videos?
@@jesseosbourne I was trying to find something similar. I'll need to keep looking I think. I'll let you know if I do find one though! :) Yes please, that would be super helpful. Also, you should set up a go fund me page or something like that so we can at-least shout you a coffee or something!
@@jesseosbourne I do remember being on birds, lizards and kangaroos i think. It was oxygen consumption, speed and another variable from memory (3 variables). I also had a lot of difficulty interpreting the graph because I didn't know whether I should rearrange the units on the side of the graph or calculate the area underneath the non-linear lines. Would be amazing if you covered something similar!
Hi Jesse, thanks so much for these videos, they are amazing! And congrats on your place at Melbourne :) I was wondering what had happened to the video you did on Scientific Notation? I remember watching it in the past but now brushing up on my maths skills it seems to no longer be in the playlist - is there a reason for this?
Thanks Anna! A few videos have had to be taken down, including the scientific notation video. A little disappointing but I'm working on redoing these videos, hopefully even better too, and reposting As a refresh for the time being, the big takeaway from that video was to convert decimal, large, & small values into scientific notation to simplify the calculations involving these values. By doing this you can tackle the 'non-10' values and then apply index laws from all the exponential components of each
Unfortunately I'm not aware of any specific graphs based question sets. In my study, I would usually practice understanding complex graphs from research papers on pubmed or through google scholar. I'll probably have to work on developing some GAMSAT graph specific question sets on the resources page though
Hi Jesse thanks so much for this video it is really helpful.. just wondering for time stamp 12.34 onward, the slope starts to be completely vertical and then horizontal, wouldn't that make the gradient = 0, which makes it neither positive or negative? thank you
Yeah sure, so the distinction to be made here is between gradient vs curvature of a graph. The gradient only refers to the slope whereas the curvature that I'm discussing there is the rate of change of the gradient itself. So at it's steepest point, the gradient is positively infinite and then it plateaus and becomes flat (gradient of 0). So through this region, the gradient goes from very positive to zero which represents a decreasing gradient = negative curvature!
Hey Robert, If you haven't already you might like to check out my Sample S3 Question Sets over on my notion page (in the video description). You can also watch the walkthrough videos for the full worked explanations You can also find good graph questions in the Des Oneil books. Otherwise, the skill of graph reading can be developed from reading graphs from research papers :)
Jesse you're the gamsat GOAT 🙏
The explanation of rates with the slopes versus linear graphs is super useful!
Awesome, glad its helped! :)
Thank-you Jesse, you're channel is INVALUABLE!!!
You, sir, are a god among men.
🤜🏻💥🤛🏻
Thank you Jesse! All the time you spend on these videos is much appreciated!
You're very welcome! Glad they're helping :)
This is an EXCELLENT video. Thank you!😊
this dude...thanks so much
No worries, man!
very well explained. Thank you
Thanks Kamal! Appreciate it
This video is a gem!
So helpful! Thank you!!
Glad to hear it Caroline! :)

Hi Jesse, are you able to do a video on log rules and their application? That will be really helpful.
Yeah sure can! Any specifics that you'd like to see included (rules based or question based etc?)
@@jesseosbourne if it is question based it would be so good. I have a bit knowledge about logs but finding it difficult to apply to the questions. Thank you in advance.
Can do. I’ll try to have this out over the next week
@@jesseosbourne thank you so very much for helping.
Hey ! were you able to do a question based?@@jesseosbourne
mate thank you so much
Glad it’s helped!

Lots of silly errors in these earlier videos haha
Yep stacked and connected graphs are becoming super popular with ACER it seems
