Mexico vs United States Grading System

How does the Mexico grading system work?

Mexican universities use a 0–10 scale where 6 is the minimum pass mark. UNAM and most public universities use this system.

⚠️ Mexican pass mark is 6/10, not 5/10.

How does the United States grading system work?

US universities use a 4.0 GPA scale as a credit-weighted average. A=4.0, B=3.0, C=2.0, D=1.0, F=0. Plus/minus grades (A-=3.7, B+=3.3) are common.

Do Mexico and the United States mark to the same standard?

No — and it is the difference in marking culture, not the arithmetic, that makes a direct comparison mislead. Here is how each country actually uses its own scale.

What a good grade means in Mexico

The 0–10 scale is used more fully in Mexico than in Brazil or the Netherlands — averages of 8 and 9 are common at good universities — which means it converts less badly than other ten-point systems but also that a high promedio is less distinguishing than it looks. The signal worth highlighting abroad is mención honorífica, since it reflects a judgement on the thesis by a committee rather than an arithmetic average, and it is not something a foreign admissions office will infer from the number.

What a good grade means in the United States

US marking is generous by international standards, and this is the mirror image of the trap that catches Indian and Chinese applicants. A US 3.5 is a good but unremarkable result, held by a large share of graduates from selective institutions — it is not equivalent to a British 3.5-out-of-4-style elite performance. Applying to the UK, an American should expect their GPA to translate to a lower-sounding percentage than instinct suggests, and that is normal rather than a downgrade.

Will a grade from Mexico get you into the United States?

United States universities typically ask for 3.00 / 4 for a taught master's — a one-to-two-year postgraduate degree made mostly of classes. On Mexico's scale that is roughly 7.7–8.2 / 10 (Bien (Good)). US graduate schools publish a 3.0 minimum near-universally. The competitive figure is the average GPA of admitted applicants across all graduate programmes at UNC Chapel Hill (gradschool.unc.edu/admissions/averagescores/) — a reference point, not a cut-off. Programmes set their own bars above the school minimum, and applicants below 3.0 are usually invited to contact the programme rather than turned away.

Muy bien (9–9.9) → approximately 3.5 GPA. Bien (8–8.9) → approximately 3.0 GPA.

What goes wrong converting grades from Mexico to the United States?

The pass marks differ — 6.0 in Mexico against 1.00 in the United States — so the two scales have different usable ranges and the middle of one is not the middle of the other.

Mistakes specific to Mexico grades

• Assuming a promedio of 8 is exceptional. Mexican averages sit higher than in many ten-point systems, so 8 is good rather than outstanding.
• Overlooking the postgraduate pass mark. Many Mexican master's programmes require an 8 average, above the undergraduate threshold.
• Leaving out mención honorífica where you hold it — it is a committee distinction that the average alone does not convey.

What should you do next, applying from Mexico to the United States?

1. Check the course, not the country. Entry requirements are set per programme and revised every cycle. The 3.00 / 4 above is the typical bar, not a guarantee — selective courses ask for more.
2. Budget for a credential evaluation. Most United States universities require your transcript assessed by an approved service before they will consider it — roughly $200 and 4–7 weeks. Our WES guide explains which report to order, since choosing the wrong one means paying twice.
3. Get your documents moving early. Universities normally require your transcript sent directly by your institution rather than as a copy from you, which takes longer than most applicants expect.
4. Read both systems in full. How Mexico grading works · How United States grading works

What do these grading terms mean?

Percentage scale

A 0–100 marking scale — but the numbers are not comparable across countries: 70% is an outstanding result in the UK and a modest one in India.

GPA (Grade Point Average)

The US way of expressing an overall grade, on a 0–4.0 scale where 4.0 is the top — so a 4.0 is roughly what a 90–100% or a First Class would be elsewhere.

Transcript

The official document from your university listing every subject you took and the grade you got — not the same as your degree certificate, and universities abroad want both.

Credential evaluation

A paid report from an approved company that restates your foreign qualification in local terms, which many US and Canadian universities require before they will assess you.

Credits / credit hours

A measure of how much a subject counts toward your degree — bigger subjects carry more credits and pull your average further.

Degree classification

A named band your final result falls into — First Class, 2:1, Distinction — used across the UK, Ireland, Nigeria, India and much of the Commonwealth instead of a single number.
