You're staring at the screen. The portal finally updated, and there it is: an 89. It’s a frustrating number. It’s the academic equivalent of a "just missed it" text. You probably want to know, flat out, is 89 a B or can you somehow wiggle that into an A?
Honestly, it depends entirely on where you are sitting. If you’re in a high school in suburban Ohio, an 89 is almost certainly a B+. If you’re at a university using a straight scale, it’s a B. But if you’re under a weighted system or a specific "curve," that 89 might actually be the highest grade in the room.
The truth is that "B" isn't a universal constant like the speed of light. It’s a social contract between an institution and a student. Most people assume the 10-point scale is the law of the land, where 90 to 100 is an A and 80 to 89 is a B. That's the standard most of us grew up with. But education is getting more granular, and that 89 is often the most contested territory in the entire gradebook.
The Standard Breakdown: Why an 89 is Usually a B
In the most common American grading system, an 89 is the ceiling of the B range. It’s often categorized as a B+ if the school uses plus/minus grading. According to the College Board, which oversees the SAT and AP programs, the standard 4.0 scale typically maps an 89 to a 3.3 or 3.5 grade point average (GPA).
It feels close to an A, but it doesn't cross the threshold.
Why? Because systems need hard lines. Without a cutoff, the entire concept of a grading tier collapses. If an 89 becomes an A, the person with an 88 will argue they are only one point away from the new A. It’s a slippery slope that teachers dread. Most syllabi explicitly state that grades are rounded—or, more often, that they aren't.
Different Scales, Different Fates
Let's look at how this changes based on the institution. At many prestigious universities, like Harvard or Stanford, the plus/minus system is the standard. In those hallowed halls, an 89 is a B+. It’s respectable. It’s fine. But it isn't an A-.

Contrast that with a school that uses a "solid" grade system. If your school doesn't do pluses or minuses, an 89 and an 80 are worth exactly the same toward your GPA. That is where the real heartbreak happens. You worked significantly harder than the student who coasted to an 80, yet your transcript treats you as equals.
Then there is the British system. If you are studying in the UK, an 89 is legendary. Over there, marks above 70 are often classified as "First Class." An 89 in a UK university context would mean you’re essentially a genius in that subject. Context is everything.
The Math of the Rounding Argument
"But it’s basically a 90!"
Every teacher has heard this. Mathematically, 89.5 rounds to 90. But does 89.4? Or just a flat 89.0?
Most learning management systems (LMS) like Canvas or Blackboard have a toggle switch for rounding. If a professor leaves it off, your 89.99 remains a B. It feels cruel. It feels like a glitch in the matrix. However, from an administrative standpoint, a line has to exist somewhere. If the syllabus says an A starts at 90.0, then 89.9 is, by definition, not an A.
Some instructors use "bump" policies. They might look at your participation. Did you show up? Did you ask questions? If you were a ghost all semester and ended with an 89, you are staying at a B. If you were in the front row every day, that 89 might "magically" become a 90.0 on the final transcript. It’s the "human element" of grading that no algorithm can replicate.

Does an 89 Actually Matter for Your Career?
Here is the secret: outside of med school admissions or highly competitive law clerkships, nobody cares about the difference between an 89 and a 90.
In the professional world, people care about your degree and perhaps your cumulative GPA. If that 89 is the difference between a 3.49 and a 3.50, it might matter for a first job at a top-tier accounting firm or a tech giant like Google. But even then, the "3.5 cutoff" is increasingly becoming a myth as companies move toward skills-based hiring.
Think about it. Have you ever asked your doctor what they got in Organic Chemistry? You don't. You care that they passed the boards and have a license. An 89 is a high-achieving grade. It signifies a "good to very good" grasp of the material. It means you showed up, you did the work, and you mostly mastered the concepts.
The Psychological Toll of the "Almost A"
There is a psychological phenomenon at play here. It’s similar to how shoppers perceive a price of $19.99 as significantly cheaper than $20.00. The "left-digit effect" makes us focus on the first number. An 89 starts with an 8. It feels like it belongs in the 80s. A 90 starts with a 9. It feels elite.
This creates a sense of "near-miss" frustration. Research in psychology suggests that people who win silver medals are often less happy than those who win bronze. The silver medalist is focused on how close they were to gold. The bronze medalist is just happy they made it onto the podium. If you have an 89, you’re the silver medalist. You’re looking at the A with longing.
How to Handle an 89 (Actionable Steps)
If you are currently sitting on an 89 and the final grades haven't been submitted to the registrar yet, you have a very small window of opportunity.

Don't just beg. Begging is annoying and rarely works. Instead, take a tactical approach.
1. Check for Grading Errors
Go back through your assignments. Is there a 0 somewhere that should be a grade? Did a T.A. miss a rubric point on page four of your mid-term? Finding a two-point error on an old quiz is much more effective than asking for "extra credit" at the last minute.
2. The Professional Inquiry
Send a short, respectful email. "I noticed I’m at an 89.0. I’ve really valued the course, especially the unit on [specific topic]. Is there any additional work or a revision I could do to demonstrate I’ve reached the A-level threshold?"
Most will say no. But some might see the initiative and find a way to help you.
3. Look at the Syllabus for "Weight"
Sometimes, a final exam can be weighted more heavily if it shows improvement. If you got a 95 on the final but your average is 89 because of a bad quiz in September, point that out. "My final exam grade reflects my current understanding of the material better than my early-semester average."
4. Acceptance
If the 89 stays, let it go. One B in a sea of grades will not sink your future. In five years, you won't even remember which class gave you the 89. You’ll just remember the skills you kept.
The question of is 89 a b is ultimately a question of boundaries. It’s a B by the book, but it’s an A in effort. Move forward knowing that the knowledge you gained is worth more than the rounding error on a spreadsheet.
Moving Forward with Your Grades
If you’re worried about future 89s, the best strategy is to front-load your effort. Aim for a 95 early in the semester so that a late-season slump only drops you to a 91. Chasing the "A" from the bottom up is much harder than defending it from the top down. Check your school's specific handbook to see if they use a 7-point or 10-point scale, as some private institutions use much stricter cutoffs where even an 89 might be a B-minus. Always know the rules of the game before you start playing.
