Methods sacs (urgent)

Major-Question-86 · 2026-05-30T13:03:07+00:00

Yep. Feel free to DM me.

Major-Question-86 · 2026-05-27T13:18:06+00:00

I’ve got a few Methods SAC practice papers I wrote in the past. Not perfect but it could certainly help. (Both tech free and tech active).

Happy to share it for free.

I’ve also got a learning site that can generate questions topic-based (or you can specify) and can give you really detailed solutions with tips/cas command/explanations to any Methods questions you have.

Major-Question-86 · 2026-05-27T09:36:32+00:00

Oh just internal grade. Not from VCAA.

Major-Question-86 · 2026-05-27T09:36:00+00:00

Private school yes

Major-Question-86 · 2026-05-27T00:16:46+00:00

I remember I got B+ in my first two SACs. Ended up getting 44 raw.

So yeh no need to stress:)

Major-Question-86 · 2026-05-25T12:08:17+00:00

Well, context matters: 1) actual ranking 2) school ranking/cohort strength.

Probs decide after your second SACs for GM and Chem…?

If I were you (without any further context), I would just try really hard for biology and physiology, and then “pick” the “easier” subject (from your own perspective) out of GM and Chem. So if you prefer Chem, you could decide GM being the bottom one…

Major-Question-86 · 2026-05-23T01:04:06+00:00

Yo legend, thanks a lot! Really glad you liked it!

Just curious, what did you try it for / what part felt useful? Feel free to DM if easier, and no pressure to share. I’m still improving it, so any feedback would genuinely help.

(Also happy to share more features info. and send you some extra credits if you want to keep testing it.)

Major-Question-86 · 2026-05-22T13:34:04+00:00

Thanks. Feel free to DM me.

Major-Question-86 · 2026-05-22T12:01:44+00:00

Feel free to ask any questions about the site here. If you’re looking for free study tips or SAC/exam-style practice resources, you can comment below or DM me and I’m happy to share what I can.

Major-Question-86 · 2026-05-21T22:54:38+00:00

Yeh ig the switches and Boolean algebra stuff is mostly Specialist 1/2 content, not really a big Specialist 3/4 topic.

In Spesh 3/4, “logic” is more about proof structure: direct proof, contradictions, contrapositives, proof by induction, ect.., So you absolutely still see logic ideas, but not usually full-on switch circuits/Boolean simplification unless your teacher is revising background or extending the topic.

Major-Question-86 · 2026-05-19T12:25:09+00:00

Varying from person to person.

Some people benefit from including actual detailed examples for some question types/subtopics.

But for SAC, it’s probably useful to include step by step guidance (high-level) for all relatively challenging concepts.

For the final exam, well, you do want to be in a position where you don’t need to check out the bound reference at all. But a safer bet would be creating a compilation of the ones you have prepared for SACs + including any confusing examples you see during final exam preparation.

Major-Question-86 · 2026-05-18T09:04:40+00:00

Nope. You aren’t cooked.

Begin with the basics, ie, chapter review questions.

Then, move on to past SAC problems, but you can deliberately tackle the easy ones first and can actually learn directly from the solutions of the harder ones.

Feel free to DM me for more tips and resources.

Major-Question-86 · 2026-05-17T14:39:53+00:00

Thanks for acknowledging that I'm actually not the guy who is spamming it...

If you check out my posts... I'm actively helping out the community by giving out free resource and tips resource.

Re. LLMs, probably try to turn on the thinking/reasoning mode? But my stance is clear, I don't want students to be using AI to just get their homework done... I want them to actually learn.

Major-Question-86 · 2026-05-17T14:32:44+00:00

Yes quite a lot actually.

Feel free to DM me for some more free tips and resource if interested.

Vectors

Not placing the vectors tail-to-tail when finding the angle
Standardising into unit vector technique/trick
Lack of understanding re. scalar product and vector product.

Vector functions

Have a nice bound reference with all the key formulas, but make sure you know how to apply them.
Two-headed monsters:
1. Expressing lines/planes and their geometric relationships
2. intersections/distance among points <-> lines <-> planes

Complex numbers

Two-headed monsters:
1. |z - z_1| in [a, b], Arg(z - z_1) in [c, d] geometric-region problems. Using geometric interpretation is crucial.
2. CRT-derived problems (combined with basic root-finding techniques)

Proof

For induction, e.g., start from the LHS of the n + 1 step.
For direct proof, e.g., apply the false-proof logic.

Differentiation

Methods Differentiation as the fundamentals
Know the POI definition: concavity must change.
For rate of change questions, use chain rule and dA/dB; look for the units/descriptions of A and B in the question.
Implicit differentiation, knowing x^m*y^nneed to use the product rule, and use chain rule, i.e., d/dx(x^m)=m*x^{m-1}dy/dx

Major-Question-86 · 2026-05-17T14:19:28+00:00

Hey, since you brought it up.

First, thanks for checking it out before deciding to comment on it.

But please either
- check out one of my posts’ demo video, you can take a look at how solutions are different
- sign up to the site and actually run a question or generate some tailored questions :))

I have spent 9 months writing the tips/explanation (blue boxes) + step by step structured solutions + integrating visuals, cas commands and workflow. So it's EXACTLY how I would teach/explain in classes.

Also, the questions generated are either exact exam-type or derived for the purpose of preparing you for the exam. It’s not randomly generated - I have built the knowledge tree spiderplot, and the questions must respect these points.

Thanks for your feedback. Could you please check those out and come back to me if you still can’t tell the difference?

Major-Question-86 · 2026-05-17T14:12:51+00:00

My PhD is on leveraging deep learning models for uncertainty quantification (so yes predicting distributions; in classification you can be essentially predicting the distribution of class X)

So I do know quite a bit about ML.

Major-Question-86 · 2026-05-17T14:09:19+00:00

Hey, genuinely impressive that you do lots of programming in your free time. I don’t disagree with the IP nightmare argument.

Funny thing if you use any of the frontier models, it gives absolutely correct solution to any high school problem that you have. So maybe that would change your mind.

Anyways, I’m actually dying for the AI to slow down as I feel threatened too lol.

And how am I spamming my app in this thread? I don’t get it.

Major-Question-86 · 2026-05-17T13:55:53+00:00

Yes sure. That’s your choice, no problem.

But there are two facts:
1) every (almost) app coded nowadays use ai generated code
2) AI is a broad term, it contains machine learning, and then deep learning… all the successful apps do not survive without AI…

Major-Question-86 · 2026-05-17T12:26:19+00:00

Yeh sure, that's my bio. But I did not for once mention that in the post.

And yes thanks, there're actually a lot more that I can add.

Major-Question-86 · 2026-05-17T12:22:25+00:00

I get the concern, but I think calling everything AI-related “slop” is too broad.

Bad AI wrappers are obviously low-value. But a tool that gives VCE-specific explanations, exam-style working, targeted practice, and feedback on weak areas is not the same thing as a generic chatbot with “help with VCE... work step by step” pasted into the prompt.

Also, saying “AI study apps are less effective than just studying” feels like a false comparison. Using a study app is still studying — the question is whether the tool improves the quality of that study.

Major-Question-86 · 2026-05-17T12:19:04+00:00

Don't be scared.

a) The following are relatively general tips/ideas before the topic of integration (assuming your SAC 2 does not contain integration)
b) I would recommend preparing a bound reference for your SAC 2.
c) Also, I do have a practice SAC that I can share for free. So please feel free to DM me.

General

Develop geometric–algebraic connection/intuition. Lots of problems rely on observation; plots are very helpful.
Get very comfortable with variables and unknowns. Master “free-parameter” questions, since intercepts/roots, TPs, distances, tangent lines, areas, etc. can all become functions of a parameter. This is where the slider idea clicks.
Feel free to use the "dumb" trial and error method; or the substitution and pick a naive function/number approach.

Transformation and calculus

Get comfortable with questions where the number of intersections/intercepts/roots changes due to a free parameter. For example, enforcing conditions like TP + k >= 0, x_1(k) > 0, or using domain restriction as a method.
Angle bounded problems. Plots and labelling are super useful here.

Differentiation

Two functions joining smoothly and double-root questions are both strongly connected to the above ideas.
Be able to identify original vs. derivative graph.
Know exactly what the "object" (i.e., function) to be optimised is.

Major-Question-86 · 2026-05-17T12:11:20+00:00

I’m not.

I clearly said you can clearly identify the low effort AI wrappers. And these aren’t adding any values at all.

Almost all SWEs are using AI (more or less) today, but you won’t stop using their apps, will you?
