DAT & PAT coaching · online · Canada

Built from the bottom. Scored in the top 1%.

I failed three university courses and high-school English. Two years later, on the Canadian DAT, I scored a perfect 30 in Biology, a perfect 30 Science total, an Academic Average in the top 0.3% of candidates, and a 98th-percentile Perceptual Ability score. Not because I'm gifted. Because I reverse-engineered how skill and learning actually work. I coach the people everyone else underestimated.

The receipts

Two sittings. Every score went up.

Most tutors show you one good score. The more honest proof is a repeatable gain. So here are both of mine, side by side. Between two sittings I raised every single section. That's the system working on a real person under real pressure. It's the same thing I'll do with you.

Canadian DAT, standard scores (1–30). Percentiles are taken from the official CDA score scale for the March 2025–February 2026 reporting period (English cohort, N = 2,593) and show the share of candidates scoring at or below each result; 30 is the maximum possible score, reached by 1.8% of candidates in Biology and 0.2% in Science. First-sitting scores are shown to make the improvement visible; the percentile column reflects the most recent sitting. Both official score reports are shown below, exactly as they were issued.

The work

PAT is the obsession. The DAT is the job.

The Perceptual Ability Test is where I go deepest. I studied how fields outside dentistry train perceptual and spatial skill, then brought those methods into the dental sections. Most of what I teach you won't find on Bootcamp or Booster, and we build it around how you actually see.

Specialty

Perceptual Ability (PAT)

Keyholes, angle ranking, TFE, hole punching, cube counting, pattern folding. We build a personal decision tree for every question type, including one core move most people never try: read the answer options before you ever look at the figure.

Section

Reading Comprehension

Reading never came easily to me. I'm an immigrant, and I failed English 12 in high school, so I had to build comprehension as a skill rather than lean on a gift: read for the message the 80/20 way, match a strategy to each passage type, chunk with smart highlighting, and train the eye mechanics most prep ignores.

Section

Biology & Chemistry

High-yield, efficient studying over brute-force memorisation, built by someone who started these subjects from near-zero.

Method

Study systems & efficiency

How to learn fast and actually retain it. The frameworks I used to go from failing classes to a near-perfect science score.

Coaching

Motivation & momentum

Motivational-interviewing-based coaching to find your real reasons and keep you moving when the prep gets long.

Performance

Test-day & anxiety

The part I struggled with most: performing on the day, not just in practice. Tools borrowed straight from years of competitive sport.

My promise

You'll walk out of your first session with at least one PAT technique you haven't seen anywhere else, or that session is free.

The story

I was the kid who started too late.

My parents wouldn't let me play organized soccer; they were sure it would wreck my grades. I started at 16, years behind everyone, and was told I'd never make a varsity team. I made one, at the University of Waterloo.

To prove a different point, I set out to bike across Canada. It took three attempts over four years, through heat waves, bears outside the tent, and rhabdomyolysis on the final ride, but I finished it. I ride to spread a little metta along the way: may all beings be happy, and may you persevere in the face of adversity.

Then an SUV T-boned me on my motorcycle and ended the soccer dream. So I pivoted to dentistry, with a transcript full of failed classes, because I'd never planned to need it.

The DAT was my one shot, and biology and chemistry were almost entirely foreign to me. So I treated studying like a sport: find what separates elite performers from average ones, then drill it relentlessly. The scores above are the result.

Here's the thing: the best players rarely make the best coaches. When something comes naturally, you often can't explain what you're actually doing to make it work. I was never the natural. I had to take every skill apart to understand it, and that is exactly what makes it teachable.

If you've been doubted, if you're starting behind, if you've got something to prove to someone, that's exactly who I want in the room.

What students say

From the people I've worked with.

“

It was immediately clear he'd put a tremendous amount of thought into the DAT, developing unique strategies of his own. He walked me through the "decision-tree" method he uses to cut cognitive load and answer more efficiently. By the end of our 1.5-hour conversation, I felt like I'd known him much longer.

Leo · SFU

“

Some of the best DAT tutoring I've had, and I've paid for tutors before. He doesn't just repeat what Bootcamp and Booster tell you; he'd gone and studied how other fields that use perceptual tests train, and pulled those strategies in. My accuracy went up almost right away.

Maria · University of Waterloo

“

Working with Jack for one hour helped me more than the 20 days I spent practising on my own. He gave me a range of highly effective tips I didn't know existed that made complex spatial concepts so much easier. A real game-changer for anyone struggling with PAT.

Ashley · McGill

“

Jack is truly the GOAT. I've reached out to many tutors and dental students, and honestly none of them care as much as he does; most are focused on the business side. Jack goes above and beyond. In our sessions I never had to worry about the clock; his priority was making sure I understood everything, not cutting it off the second time ran out. This isn't an advertisement; I just genuinely recommend him to anyone struggling to prepare for the DAT.

Dorsa · University of Manitoba

“

He's literally just like me. He'd been lost and confused too, and figured out how to raise his score in every part. He helps you avoid extra burden and confusion. I won't talk to anyone else about my DAT but him.

Reading Comprehension: Field Notes

The exact approach I used to take RC from a weakness to a 25 (90th percentile): context-building, the 80/20 read, highlighting that actually helps, choosing a strategy by passage type, and the eye-mechanics work most prep skips entirely.

If money is the only thing standing between you and the help.

For people in genuinely hard circumstances. Tell me your situation in the form below and email me any supporting context. I read every one myself. No fixed number of seats: if I can help, I will.

Payment is by Interac e-Transfer to jack.zhang.jz43@gmail.com, arranged after our intro call confirms we're a fit. No bundles, no lock-in. Book a session at a time, only when it's useful to you.

25%

The 25%

A quarter of every fee goes back out.

For every paid session, 25% of the fee is donated, and here is exactly how it splits. Half of that (12.5%) goes to a charity you choose from a vetted list I keep. The other half (12.5%) I distribute myself to local causes like the UBC Student Food Bank and food and supplies for people living rough in downtown Vancouver. Either way, you see the proof: I show you where every dollar landed, with photos of exactly which meals, socks, and blankets went where, plus the receipts. No vague promises.

Details

Good to know.

How do sessions work?+

One hour, one-on-one, online over Zoom. The first intro call is 15 minutes and free, so we can both check the fit before you commit to anything.

How do I book, and what about availability?+

Start by filling out the application above. My availability changes week to week, so once we've clicked on the intro call I'll send you the times that work that week and we'll lock one in.

How do I pay?+

Interac e-Transfer to jack.zhang.jz43@gmail.com, arranged after the intro call. Pick the pay-what-fits tier that honestly matches your situation. No bundles or lock-in. Pay one session at a time.

What's the cancellation policy?+

Full refund up to 48 hours before a session. Need to move it? You can rearrange up to 24 hours before. Once we're more than 15 minutes past the agreed start time, that session isn't refundable.

Do you only coach PAT?+

No. PAT is my specialty and my favourite, but I also coach Reading Comprehension, Biology, General Chemistry, study systems, motivation, and test-day performance.

What if we're not a fit?+

That's exactly what the free intro call is for. If I don't think I'm the right person to help you, I'll say so and point you toward something that suits you better. I'd rather do that than take a session I can't make count.
