Stacy Blackman GMAT Focus Math Cheat Sheet Review

Stacy Blackman's GMAT Focus Math Cheat Sheet is a six-page PDF that costs $9.99, and it is worth that if you want one printed reference for quant formulas and you understand what it leaves out. It covers math only, so it speaks to 21 of the 64 scored questions on the exam, and you cannot see a single line of it before you pay.

That second point is why this review exists. Search for this product and seven of the first ten results belong to the company selling it. Nobody independent has looked at it, so we read the store page, Stacy Blackman's tutoring page and its free GMAT library on 20 September 2026, and checked every coverage claim against what GMAC currently says is on the test.

Stacy Blackman GMAT Cheat Sheet Overview

Stacy Blackman Consulting is an MBA admissions firm. Test prep is one of its side services, and this sheet is the only test prep product it sells without booking a person's time.

The store page describes it as a "brand-new masterpiece of tips, tricks, and formulas" written by Anthony Ritz, the firm's Director of Test Prep, and calls it "the only cheat sheet that includes every essential rule and strategy you need". The format line is blunter and more useful: "Format: 6 page PDF". Price: 9.99 USD. The suggested use is the honest part of the copy, which tells you to review it on the subway and refer to it when analysing your practice tests.

What the page says you get:

• Six pages of GMAT Focus math rules, formulas and strategies
• Word problems, number theory and algebra
• Probability, combinatorics and statistics
• A PDF delivered through an e-junkie checkout, not a Stacy Blackman account

What the page does not give you: a table of contents, a sample page, a page count per topic, a refund policy, an access period, or any indication of how dense those six pages are. The thumbnail on the page is the closest thing to a preview, and it is too small to read beyond a heading or two.

Stacy Blackman GMAT Cheat Sheet Review For 2026

A math sheet reaches one of the exam's three sections

The product is labelled for GMAT Focus, and the topic list is consistent with what the exam now tests. GMAC describes Quantitative Reasoning as measuring "your algebraic and arithmetic foundational knowledge", delivered as 21 Problem Solving questions with no calculator. Word problems, number theory and algebra are exactly that material.

The scope question is what that section is worth. GMAC's exam structure page puts the test at 64 questions in 2 hours and 15 minutes: 21 Quantitative Reasoning, 23 Verbal Reasoning and 20 Data Insights. The three sections are weighted equally in the 205 to 805 total score, per GMAC's scoring page.

Two consequences follow, and neither is a criticism of the sheet's content. The first is that a math reference is worth about a third of your score, so nobody should treat $9.99 of formulas as a study plan. The second is subtler: Data Sufficiency is no longer a quant question type. GMAC lists it under Data Insights, the section where you do get an on-screen calculator. A sheet built around quant formulas is not aimed at the part of the exam where most candidates lose data-handling points.

What you cannot check before you pay

Six pages is the entire specification. There is no sample, no contents list and no word on how the six pages divide between six advertised topics.

That matters more here than it would for a $300 course, because a cheat sheet is judged almost entirely on layout. A good one fits the rules you forget onto a surface you can scan in fifteen seconds. A bad one is a textbook chapter in eight-point type. Nothing on the store page lets you tell which of those you are buying, and we have not bought it, so this review makes no claim about the quality of the pages themselves.

The purchase terms are equally thin. Checkout runs through e-junkie rather than a Stacy Blackman account, so the file is a download rather than a library you log into. The page states no refund policy and no access period. For $9.99 the downside is small, but you are buying unseen from a company that publishes refund terms elsewhere on its own site.

A side product from an admissions firm, with an odd signal next door

The author credential is real. Anthony Ritz is the firm's Director of Test Prep, and Stacy Blackman's test prep page shows the price of his department's time: a $600 trial package for two hours, then $350 an hour, dropping to $275 an hour if you buy thirty. The same page sets a two-hour minimum and states there are no refunds for unused hours. Against that, $9.99 is the only way to buy anything from this test prep team without spending $600 first.

The signal that gives us pause sits on the same website. Stacy Blackman's free GMAT Files library, which ranks fourth for this product's own name, is still organised around Sentence Correction, analytical writing, Integrated Reasoning, Data Sufficiency as a quant type and a plane and coordinate geometry primer. None of those describe the exam GMAC runs today. The same page states that "the maximum score that can be achieved on the exam is 800", while GMAC's current scale is 205 to 805.

The paid sheet is the Focus-current item and the free library around it is not, which cuts both ways. It is a point in favour of the $9.99 purchase if you want current material from this firm. It is also a reminder that GMAT content is a sideline here, maintained where it sells and left alone where it does not. If you want a provider whose whole business is the quant section, our Target Test Prep review is the comparison to read.

Pricing

One product, one price, and it is the cheapest thing Stacy Blackman sells.

Every figure in that table was read on 20 September 2026, the sheet's price from the store page and the tutoring ladder from the test prep page, both linked above. Read the table as a ladder rather than a menu. The sheet costs less than two percent of the cheapest way to speak to the person who wrote it, and the firm requires the $600 trial review before it will sell you hourly packages at all.

The honest comparison is not with tutoring, though. It is with free. The other three GMAT cheat sheets in our GMAT cheat sheets directory are free downloads from companies whose main business is the GMAT, and any of them will cover exponent rules and averages as well as a paid sheet will. What $9.99 buys is a single Focus-labelled set of six pages, written by one person, instead of a formula list assembled from a forum thread. Whether that is worth ten dollars depends on how much your time is worth and how close your test date is. Our review methodology explains how we weigh price against what a product verifiably includes.

Who Stacy Blackman's Cheat Sheet Is Best For

• Candidates who print things. The format is a six-page PDF built to live on a desk or in a bag, and that is a genuine use case a question bank does not serve
• Late-stage quant reviewers who have done the learning and want one surface to scan the week before the test
• Anyone already working with Stacy Blackman on admissions, where $9.99 to see how its test prep team thinks is a reasonable sample
• Students who want Focus-era material specifically, since the sheet is labelled for the current exam rather than carried over from the retired one

Who should skip it: anyone at the start of their quant preparation, anyone whose weak section is Data Insights or Verbal, and anyone who would use a free sheet just as happily. If you have not yet diagnosed where your points are going, start with our GMAT study guide and some free GMAT quant practice questions before spending anything.

When You Might Look Elsewhere

• You want the same content free. The Target Test Prep equation guide and the GMAT Club Focus formula sheet cover the same quant ground at no cost, and the Kaplan quicksheet is another free option from a full-service test prep company
• You need to see it before you buy it. None of the free alternatives asks you to pay unseen, which is the fairest argument against this product
• Your problem is practice, not recall. A cheat sheet has no questions in it. The GMAT Official Question Bank is the material to buy when you need real exam questions rather than formulas
• You need help across the whole exam. Quant is one of three equally weighted sections. Start from the GMAT hub and pick prep that matches the section costing you points

Final Verdict

We rate it 3.2 out of 5. The price is honest, the topic list matches what GMAC says Quantitative Reasoning now is, and the author runs the test prep department of a firm that charges $350 an hour for the same expertise. It loses points for what is missing around the product rather than for the product itself: no preview, no contents, no refund policy, no practice, and free competitors that cover the same rules. It is a sensible ten dollars for a specific kind of student, and no student needs it.

Stacy Blackman GMAT Cheat Sheet FAQs

What is the Stacy Blackman GMAT cheat sheet?

It is a six-page PDF of GMAT Focus math rules, formulas and strategies, written by Anthony Ritz, the Director of Test Prep at Stacy Blackman Consulting. It sells for $9.99 through the firm's online store and covers word problems, number theory, algebra, probability, combinatorics and statistics. There is no video, no practice set and no software attached to it.

Does it cover the whole GMAT?

No. It is a math reference, so it addresses Quantitative Reasoning, which GMAC counts as 21 of the 64 scored questions on the exam. Verbal Reasoning is 23 questions and Data Insights is 20, and this sheet covers neither. All three sections carry equal weight in your 205 to 805 total score.

Can I see the sheet before buying it?

Not in any meaningful way. Stacy Blackman publishes a small thumbnail of one page and no sample, no table of contents and no breakdown of how the six pages are divided. The store page also states no refund policy, so treat the $9.99 as spent once you click through to the checkout.

Is a paid GMAT cheat sheet worth it when free ones exist?

Only if you value one curated, current document over assembling your own. Three other GMAT cheat sheets in our directory are free, including guides from companies that teach the GMAT full time, and formulas do not change between providers. The case for paying is that this one is written for the Focus exam by a single named author, in a fixed six-page format you can print.

Who is Anthony Ritz?

He is Stacy Blackman Consulting's Director of Test Prep, named as the author on the product page. His department sells GMAT and GRE tutoring starting with a $600 two-hour trial review, after which hourly rates run from $350 down to $275 for thirty hours. The cheat sheet is the only product of his the firm sells outright.
