My son started at 157. He's at 227 now. We're still on the road.

The number that started everything

When my son completed his first diagnostic practice paper, his projected TSS was 157.

Perth Modern wants you above 252. Willetton is around 243. Even Carine SHS — one of the more accessible selective schools — sits at 229. 157 was a long way from any of those numbers. That was confronting. But it was also the truth, and the truth is the only thing worth working from.

I'm an Enterprise Architect. I've spent 20+ years building data systems for large organisations. When I see a number I don't like, I don't panic — I look for the gap, and I build a system to close it. That's what I did here. Except this time it was my son.

What I couldn't find

I searched for something that would track his progress properly — not just give a score once a month and leave us guessing whether the work was actually helping. I wanted to know: which section is dragging the total down? Is Writing improving or stalling? Is he finishing papers on time?

What I found was mostly coaching classes (3–4 hours on a weekend) or printed mock tests I'd mark myself at the kitchen table. Neither gave me data. Neither told me whether what we were doing was working. So I built what I needed.

157 to 227 — 8 attempts, +70 points

My son practices in short, focused sessions — 20 to 30 minutes, a few times a week. No weekend classroom, no external tutor. Just the platform, consistent effort, and me checking his dashboard every day to see where we are.

After every session, we sit together and go through the results. Not just the score — the questions he got wrong, and more importantly, why he got them wrong. The platform shows the correct answer and the explanation for each one. That conversation after the session is where the real learning happens. He understands the mistake, we talk through the reasoning, and the next attempt is better for it.

I built that loop into the platform deliberately — practice, instant results, explanation, discussion, next attempt. It's not just a test tool. It's a continuous improvement cycle. Each session feeds the next one.

After 8 full mock attempts, his projected TSS is 227 — up 70 points from where he started. Here's what that actually looks like on the dashboard:

His actual Score Trend from the dashboard — 8 full mock papers, 22 May to 8 June. Target: 252 for Perth Modern.

The trend matters more than any single result. You can see one dip in the middle — that happened during a week where practice was less consistent. That dip told me something. That's the point of tracking.

The projection: ~273 — and why I hold it loosely

Based on his current trajectory, the platform projects his exam-day score at around 273. That would put him above every selective school cut-off we're tracking — including Perth Modern at 252.

His actual School Readiness screen. Projection: ~273. Currently qualifies for Carine SHS (229). Perth Modern needs +21 more points.

I hold that 273 loosely. It's a projection based on current performance — not a promise. It updates every time he submits a paper, and it will shift if practice becomes less consistent or if harder papers reveal gaps. That's not a flaw in the system. That's the system working correctly.

He still needs +21 points to reach Perth Modern. That's real and that's where our focus is.

What the data is telling us right now

The GATE Readiness Score sits at 62/100 — rated "On Track" overall. But the section breakdown is where the real story is:

His actual GATE Readiness card. Reading Comprehension and Speed are strong. Writing and Consistency are flagged At Risk.

Reading Comprehension: Strong. Speed and pacing: Strong — he finishes papers within time limits comfortably. But Writing is At Risk, and so is Consistency. Those two are connected.

The consistency chart tells the fuller picture:

Score Consistency across sections. AR and QR are Variable — meaning results swing too much between attempts. ±8% or lower is exam-ready.

Abstract Reasoning and Quantitative Reasoning are both flagged Variable — ±19% and ±23% swings between attempts. That tells me the knowledge is there on good days, but it's not locked in yet. The platform's focus message this week: "Your scores vary a lot between attempts — aim for steady daily practice to build consistency."

That's exactly what I'm working on with him. Not more hours — more regular sessions. The data is clear about what moves the number.

What this isn't

I want to be clear about what WA GATE Prep is not.

It's not a magic shortcut. 157 to 227 took months of consistent practice, adjusting focus based on the data, and being honest when something wasn't working. There's no version of this where you skip the work and still get the result. What the platform does is make sure the work is pointed in the right direction.

It's also not designed to pressure kids. My son does 20–30 minute sessions. Short and focused is enough when you know which 20 minutes matter most. The platform tells you that. The readiness card and consistency scores tell you exactly where to spend the next session.

We're still on the road

My son sits the ASET in 2028. We have time, but we're not coasting — the consistency flags are real and we're working on them. I'll keep improving the platform alongside his preparation, adding features based on what the data shows and what Perth families actually need.

If your child just got a score that scared you — 157, or lower — I built this because I've been exactly there. The number tells you where to start, not where you'll finish.
