FAQ
- Are the estimated grades identical to actual score sheets?
- No. This tool uses pre-compiled average grade boundaries. Real scores depend on yearly exam difficulty and standard deviations, so use this as a reference only.
- Does the Korean History score affect the grade-cut predictions for other subjects?
- Korean History is graded on an absolute (pass/fail-style) scale, so it only produces a grade — not a standard score or percentile — and it has no effect on the percentile or standard-score calculations for the relatively-graded subjects. It's shown separately, purely to check whether you meet the minimum requirement.
