Free UDF Course for VCE Methods | HBE Academy

Free · VCE Methods

The 10 UDFs every Methods student should have on their CAS.

Lifted straight out of our paid Unit 3 and 4 Methods course. A free standalone module, taught by Amna, ready to install in under ten minutes.

One function. Exact values. More marks.

UDFs

Lessons

Minutes

The math of one function

A routine Methods question without a UDF takes 90 seconds. With a UDF, it takes seconds.

Save 30 seconds per routine question. Across a 2-hour Methods exam, that's back-of-paper separator questions answered with a clear head instead of a fried one.

Without a UDF

90 sec

Three separate CAS commands, per question.

Mistype a coefficient, start over
Decimal output, back-solve by hand
Re-run commands to double check
Energy gone before the big questions

With a UDF

5 sec

One function. Exact answers on screen.

Turning point, intercepts, discriminant
Exact values, never decimals
No re-running, no second guessing
Clear head for separator questions

🧠 Students who use UDFs well aren't being lazy. They know where the marks come from.

The full list

Here's exactly what you'll install

Ten curated UDFs organised across the three Methods sections. Each one paired with a sample exam question so the install actually turns into marks.

Functions & Coordinate Geometry 2 UDFs

PointInfo(a,b,c,d)

Distance, midpoint, gradient, line equation, and perpendicular bisector of two points. All from one function.

quadall(a,b,c)

Turning point, x-intercepts, and discriminant of any quadratic.

Calculus 3 UDFs

avgroc(f,a,b)

Average rate of change of a function over any interval.

avgval(f,a,b)

Average value of a function over an interval.

newtonmethod(a,f)

Newton's method iterations with one command. Feed the output back in for the next estimate.

Probability 5 UDFs · highest leverage

binom(n,p)

Mean, variance, and standard deviation of a binomial distribution.

hyper(a,n,k,x)

Hypergeometric probability in a single function call.

continuous(f,a,b)

Mean, variance, and SD of a continuous probability distribution.

stats_prob(n,p)

Sample proportion mean and standard deviation.

norm_func(x,u,σ)

Writes out the equation of a normal distribution.

Amna, lead Maths Methods tutor at HBE Academy

Meet Amna

Amna is the lead Maths Methods tutor at HBE Academy. She built this module on the exact 10 UDFs she used to get through Year 12, each one paired with a sample exam question so the download actually turns into an exam tool.

Her philosophy: UDFs aren't about being lazy with the maths. They're about knowing where the marks come from, and refusing to waste your sharpest thinking on questions a calculator can handle.

"You don't need UDFs. But if you use them well, they save your energy for the questions that actually decide your score."

Full transparency

This is our paid Methods course, minus the paywall.

The UDF module is the exact module from our paid HBE Unit 3 and 4 Methods course. We've pulled it out, polished it, and released it as a free standalone module so you can see the quality before you commit to anything.

No catch. The full module is yours to keep. If it helps, our full Methods course is where we go deeper. If not, keep the UDFs and ace your SAC.

Common questions

Good questions answered

Is this actually free?

Yes. Full module, no paywall, no upsell gate. If the module helps, our full Unit 3 and 4 Methods course is where we go deeper. That decision is entirely up to you.

What calculator do I need?

TI-Nspire CX or CX II, the CAS model you use for VCE Methods. The UDFs work on both.

Do I need the TI student software?

No. There's a manual install walkthrough that takes under 10 minutes. You type each UDF once, save to your mylib folder, refresh libraries, and you're set for the year.

How long does the course take?

About 45 minutes end to end, plus 10 minutes of install time. Most students watch the UDF sections as they hit each Methods unit rather than all at once.

Are UDFs allowed in the VCE Methods exam?

Yes. VCAA allows programmable functions on the CAS. Your calculator, your UDFs, your exam marks.

I'm only in Year 11. Will this help me?

Yes. Install the Functions UDFs now and use them on textbook questions. Amna recommends using UDFs from day one so they feel native by the time you hit SACs and exams.
