Frequently Asked Questions

How to Calculate Your Grade

Enter your scores and their weightings to calculate your overall grade or GPA. Useful for students tracking coursework, assignments and exam contributions to a final module grade.

Weighted average grading

Most UK universities and schools use weighted grading — different assessments contribute different percentages to the final grade. For example: 30% coursework + 70% exam. If you score 65% on coursework and 72% on the exam, your grade is (65 × 0.3) + (72 × 0.7) = 19.5 + 50.4 = 69.9%.

UK degree classification boundaries

First Class (1:1): 70% and above
Upper Second (2:1): 60–69%
Lower Second (2:2): 50–59%
Third: 40–49%
Pass: Below 40% (varies by institution)

What is a weighted grade average?▾

Each assessment contributes proportionally to the final grade based on its weight.

How do I convert % to a UK degree classification?▾

70%+ = First. 60–69% = 2:1. 50–59% = 2:2. 40–49% = Third.

What is GPA?▾

Grade Point Average — the US grading system where A=4.0, B=3.0 etc.

What grade do I need on my final exam?▾

Enter your completed work with its weights, then pick a target. If your weights add up to less than 100%, the remaining weight is treated as your final, and the calculator shows the score you need to hit your goal.

How is a weighted grade calculated?▾

Each score is multiplied by its weight, those are added together, and the total is divided by the sum of the weights. Leave the weights blank for a simple average.

Is 70% a first-class degree?▾

In the UK, 70% and above is usually a First (1st). 60–69% is a 2:1, 50–59% a 2:2, and 40–49% a Third.

How do I convert a percentage to GPA?▾

On the common US 4.0 scale an A is about 4.0, B is 3.0, C is 2.0, D is 1.0 and F is 0. See the percentage-to-GPA table for the ranges.

Is 70% an A in the US?▾

No — in the US, 70% is usually a C. In the UK, 70% is a First-class result. Use the UK / US switch to see the right grade for your system.

What's the difference between UK and US grading?▾

UK degrees use classifications: First (70%+), 2:1 (60–69%), 2:2 (50–59%) and Third (40–49%). US schools use letters A–F on a 10-point scale — A is 90+, B 80+, C 70+, D 60+, F below 60 — plus a 4.0 GPA.

UK vs US grades

The same percentage means very different things in each system — in the UK 70% is a First, while in the US it's only a C. Use the UK / US switch at the top to show the grade for your system.

Percentage	UK class	US letter	GPA
90–100%	First (1st)	A	4.0
80–89%	First (1st)	B	3.0
70–79%	First (1st)	C	2.0
60–69%	2:1	D	1.0
50–59%	2:2	F	0.0
40–49%	Third (3rd)	F	0.0
0–39%	Fail	F	0.0

What do I need on my final?

When your weights don't add up to 100%, the missing weight is treated as your upcoming work (like a final exam). Enter your completed assessments with their weights, then pick a target. The calculator finds the score you need with: needed = (target × 100 − points so far) ÷ remaining weight, where points so far is each score multiplied by its weight. If the answer is over 100% the target isn't reachable; if it's zero or below, you've already secured it.
