I'm a two-time perfect scorer.

I'm Vaibhav Sharma. I coach the digital SAT in a small batch, a large batch or one-on-one, and I built the platform my students practice on between our sessions. This page is who I am and how I work, so you can decide whether I'm worth your time before you enquire.

The short version

I'm a two-time perfect scorer. I'm a certified digital SAT trainer, and I've been in the test-prep space for the last eight years. I now coach the digital SAT three ways: a small batch of 5 to 8 students, a large batch of 100 to 200, and one-on-one. The small batch and one-on-one both include full access to the PrepGenix platform. PrepGenix only enrols students who qualify, and we share the fee when you enquire.

What the perfect score tells you, and what it doesn't

A perfect score means I've solved every kind of question this test asks under real time pressure, twice. That matters, because the fastest route through an SAT Math question is rarely the route a textbook teaches, and you only find those routes by sitting the thing at full speed.

Here's what it doesn't mean: that I'm automatically a good teacher. Plenty of perfect scorers are terrible at explaining themselves, because the thing they're best at is the thing they never had to think about. I've watched it happen. The reason I train, certify and keep teaching across three different exams is that scoring and teaching are separate skills, and only one of them is the one you're paying for.

So judge me on the second one. Everything I know is published free on this site: 61 guides and counting. Read a few before you enquire. If the writing doesn't teach you something, don't pay me.

How I coach

One principle: a session should change what you do tomorrow. A pep talk doesn't do that, and neither does repeating what a video already covered.

In practice that means we start from evidence, not vibes. You take a diagnostic, I read the domain pattern, and we work on the thing that's costing you the most points rather than the thing that feels worst. Those are different, more often than students expect. A student who "hates Reading" is frequently losing more points to Advanced Math and doesn't know it, because missing questions in a section you dread is memorable and missing them in a section you tolerate is not.

Then it's mechanism over memorization. The digital SAT is adaptive: your performance on the first module decides which second module you get, which decides the score range available to you. Students who understand that make better decisions about guessing and flagging than students who've memorized a list of tips. Understanding the machine beats memorizing outputs of the machine.

And because the person paying for this is usually a parent, not the student, I don’t make them guess. Every week I send a written progress report on what we covered, how the mock scores and section trends are moving, what’s still costing points, and whether the daily practice quota is being done. You find out while there’s still time to act on it, not when the official score report lands.

Why I built the platform

Because the problem with coaching, in any format, is the other six days of the week.

An hour with a good coach shows you the fastest path to a question. It does nothing to guarantee you walk that path on Tuesday when nobody's watching. Homework sheets don't solve it. They're not adaptive, they don't score you, and they can't tell either of us whether you're improving or just busy.

So I built the thing that does: a full adaptive engine with Bluebook-style modules, instant scoring, a domain-by-domain breakdown, and a study plan that rebuilds itself around your weak spots. Coaching shows you the path; the platform makes sure you walk it daily. You can take a full practice test free without ever speaking to me.

What I publish that most prep companies won't

Test prep is an industry with a strong incentive to be vague, because vagueness never gets you caught being wrong. I've gone the other way, and it's the clearest thing you can judge me on:

A page that only ever tells you good news isn't being kind to you. It's protecting itself.
