The MCAT 520 Guarantee: What These Promises Actually Mean

Type “MCAT 520 guarantee” into a search bar and you will find prep companies promising you a score, or your money back. It sounds like the safest purchase in test prep. Someone else is taking on the risk, so what is the harm?

The harm is in the fine print, and the fine print is the entire product. A guarantee is a legal document written by the company that has to pay it, which means it is written to be paid as rarely as possible. That is not a scandal. It is simply how guarantees work. But it means the headline number tells you almost nothing, and the terms tell you everything.

I scored a 527, I run an MCAT tutoring company, and we offer a score guarantee of our own. I also give away six full MCAT books and a question bank for free, so I am not trying to sell you on a promise. What I want here is for you to be able to read any guarantee, including mine, and know exactly what you are and are not being offered.

Why companies offer guarantees at all

A guarantee does two jobs, and neither of them is “give you your money back.”

First, it moves perceived risk. Buying expensive prep is scary, and a guarantee lets you tell yourself the downside is covered. That feeling is worth more to the seller than the rare payout ever costs them.

Second, it signals confidence. A company willing to attach terms to its teaching is telling you it expects those terms to be met. That signal is real and worth something, as long as you confirm the terms are actually reachable and the payout is actually worth having.

Both of those are legitimate reasons to offer a guarantee. They are also the reasons a guarantee exists to help sell, not to pay out. So read it like a buyer, not like someone being reassured.

The four things to check in any guarantee

Before you believe any score guarantee, read for these four things. If a company will not show you all four in writing, that is your answer.

What to check	The reassuring version	What the fine print often says
What is promised	”We guarantee a higher score.”	A point increase from a baseline the company defines, not a specific number like 520, and rarely an absolute score at all.
What you must do	”Just study with us.”	Attend every session live, finish every assigned full-length, complete a set number of practice questions, and submit homework on time.
What you get if you miss	”Money-back guarantee.”	Usually more free access: extended resources, extra materials, sometimes discounted tutoring hours. A cash refund only in narrow cases.
Who even qualifies	”Open to our students.”	Starting-score windows, first-time-customer rules, a minimum number of hours in a single purchase, and tight deadlines to submit your score.

Notice what happens when you read all four together. A promise that sounds like “hit your dream score or get a refund” often resolves to “increase your score at all, from a starting point we define, after you complete every requirement, and we will give you more of our product for free.” That can still be a fair deal. It is just a very different deal from the one the headline implied.

A guarantee is only as good as the teaching behind it

Here is the part the guarantee itself will never tell you: the promise is worth nothing if the teaching does not work.

Think about it from the company’s side. If the instruction reliably raises scores, the guarantee almost never pays out, so it costs the company nothing to offer generous terms. If the instruction is weak, the company writes strict terms so it still almost never pays out. Either way, you cannot use the guarantee to judge the prep. A strong guarantee bolted onto weak teaching is a marketing expense, not a safety net.

So evaluate the prep first, on its own merits: who is teaching, what their scores are, how they diagnose your weaknesses, and whether they adapt when you fail something. My post on choosing between a course, books, and tutoring walks through that decision without a guarantee anywhere in it, because the guarantee should be a tiebreaker between two options you already like, never the reason you picked one.

If two programs look equally good and one attaches honest, reachable terms, let that break the tie. That is the correct weight to give a guarantee.

How ours works, in plain terms

We call it a Score Increase Guarantee, and every term is posted openly on our score increase page. I want you to read it applying the exact four checks above, so here is our version against each.

What we promise is a score increase from your verified baseline, not a specific number. Our top tutoring track is named 520+, but a program name is an aspiration, not a documented goal, and our terms say so directly. The guarantee is about moving your own score, not hitting a headline figure. There is even a published cap on how ambitious a guaranteed goal can be, so nobody can read “520+” and claim that a 520 was promised to them.

What you must do is real work, and it is listed in full: attend your tutoring hours live, complete every full-length your tutor assigns, finish a set number of practice questions for each hour you purchased, and submit your assignments on time. Miss those, and the guarantee is void. We say that plainly because I would rather you know the deal now than feel misled later.

What you get if your score does not increase is more access, not a refund. We do not issue cash refunds under the guarantee, and we say so in the first paragraph of the terms. The remedy depends on your tutoring tier:

Tutoring tier	Minimum to qualify	If your score does not increase
Foundations (510+)	30 hours in a single purchase	One month of extended online resources
Standard (515+)	30 hours in a single purchase	Two months of extended online resources
Premium (520+)	40 hours	Three months of extended resources, a short Recovery Consultation with a senior tutor, and the option to buy additional hours at a discount

Who qualifies is capped, and the caps are published: you buy a qualifying package directly at the standard rate, submit a baseline early, attend live rather than by recording, and take your official MCAT within a set window. First-time customers only. None of that is buried in a footnote, because burying it would defeat the point.

Is that a weaker-sounding promise than “score 520 or your money back”? On the headline, yes. In reality, it is the honest version of the same structure every serious guarantee uses, with the fine print moved to the front. I would rather lose a sale to a flashier promise than win one you did not fully understand.

The bottom line

A score guarantee is a tiebreaker, not a reason to buy. Run the four checks every time: what is actually promised, what voids it, what you get if you miss, and who qualifies. Then judge the teaching on its own, because that is what actually moves your score.

The surest score increase was never the guarantee. It is good practice and good teaching, repeated until the exam stops surprising you. If your score has stalled and you are weighing your options, our guides on what a good MCAT score really is and whether to retake will help you more than any promise on a sales page. And if you want a person watching how you actually reason through passages, that is what our tutoring is for, guarantee or not.
