Test Grade Calculator
Enter the number of correct answers (or points earned) and the total (or maximum) to get the percentage, a letter grade and a pass/fail call. Supports the US A–F scale, the US plus/minus convention, and UK honours classifications (First / 2:1 / 2:2 / 3rd) — handy for teachers grading papers and students estimating where they land.

Grade

US standard uses 90/80/70/60 cut-offs; the plus/minus convention splits each letter into three bands (e.g. A+ ≥97, A- 90–92). UK honours uses 70/60/50/40 for First / 2:1 / 2:2 / Third (QAA framework).
Formula
Percentage = correct ÷ total × 100 US standard: A ≥ 90, B ≥ 80, C ≥ 70, D ≥ 60, F < 60 US plus/minus: A+ ≥ 97, A 93–96, A- 90–92, B+ 87–89, B 83–86, B- 80–82, C+ 77–79, C 73–76, C- 70–72, D+ 67–69, D 63–66, D- 60–62, F < 60 UK honours: 1st ≥ 70, 2:1 60–69, 2:2 50–59, 3rd 40–49, Fail < 40 Reverse: to hit X% you need at least ⌈X% × total⌉ correct
- · Percentage uses correct ÷ total directly — points need not be 1 per question (e.g. 8.5 / 10 marks = 85% works fine).
- · US A–F is the standard K–12 scale with cut-offs at 90/80/70/60; anything under 60 is F (fail).
- · US plus/minus is the most common college 4.0-scale variant — each letter splits into three bands (A+ ≥ 97, A 93–96, A- 90–92, etc.). Schools sometimes vary the cut-offs by ±1 point — adjust to your institution if needed.
- · UK honours: 1st ≥ 70, 2:1 60–69, 2:2 50–59, 3rd 40–49, fail < 40 (source: QAA UK Quality Code for Higher Education). A 2:1 is the minimum that most UK graduate schemes / postgrad programmes ask for.
- · For the Hong Kong HKDSE (1–7 levels including 5**, 5*, 5), the level cut-offs are set yearly by HKEAA and cannot be mapped from a flat percentage — use the dedicated HKDSE Best 5 Calculator for those.
- · Result is just the raw score — no curve, scaling or bonus adjustments. Your school or institution's published grading policy always overrides this tool.

Frequently asked
What's the difference between the US A–F scale and the plus/minus version?
The plain A–F scale has five letters (A B C D F) with cut-offs at 90/80/70/60 — common in US K–12. Most US colleges use a finer plus/minus version that splits each letter into three bands: A+ ≥ 97, A 93–96, A- 90–92, B+ 87–89, B 83–86, B- 80–82, and so on. These map to GPA values like A = 4.0, A- = 3.7, B+ = 3.3, B = 3.0. Institutions sometimes shift cut-offs by ±1 point — check your school policy.
What do the UK honours classifications (1st, 2:1, 2:2, 3rd) mean?
UK undergraduate honours degrees use four bands: First-Class (1st) ≥ 70%, Upper Second-Class (2:1) 60–69%, Lower Second-Class (2:2) 50–59%, Third-Class (3rd) 40–49%, with anything below 40% a fail. A 2:1 (pronounced "two-one") is the minimum entry bar for most UK graduate schemes, postgraduate taught programmes, and professional training in law and accounting. Oxbridge and other G5 postgraduate programmes typically expect a First. Source: QAA UK Quality Code for Higher Education.
If I want an A (90%) on a 50-question test, how many do I need correct?
90% × 50 = 45 questions. So you can miss at most 5 to still get an A. If the test is graded on points rather than questions (e.g. out of 100), use 90% × 100 = 90 points. The calculator shows this "minimum correct for 90%" target at the bottom automatically.
Can I use this for HKDSE (Hong Kong DSE)?
No — HKDSE uses 1–7 levels (5**, 5*, 5, 4, 3, 2, 1, Unclassified) and the cut score for each level is set annually by HKEAA based on the cohort's performance, not by a fixed percentage. Use the dedicated HKDSE Best 5 Calculator for DSE points.
