성적 관련 용어
- GPA (Grade Point Average)
- A numerical expression of a student's academic performance. In the US, it typically scales up to 4.0. It is a widely used metric for university admissions, job applications, and scholarships globally.
- Weighted Average
- An average where each data point is assigned a "weight". In grade calculation, the "credits" of each course serve as the weight. Courses with more credits have a greater impact on the final GPA.
- Grading Scale
- The system used to convert a test score (e.g., out of 100) into a grade (e.g., A, B, C or 4.0, 3.0, 2.0). These scales vary significantly by country and university. For example, Germany uses a scale where 1.0 is the highest mark.
- Credits / Credit Hours
- A value representing the required study time or importance of a course. A course that meets more frequently usually grants more credits. When calculating GPA, the grade point is multiplied by the credits, making it a crucial factor.
- Target Grade Calculation
- A reverse-calculation method used to find out what score you need on your remaining exams to achieve a desired final grade, based on your current grades and their weight in the syllabus.
자주 묻는 질문 (FAQ)
- Q.입력한 성적 데이터가 서버로 전송되나요?
- 아닙니다. 모든 계산은 사용자의 브라우저 내에서만 이루어집니다. 개인 정보나 성적 데이터는 외부 서버로 전송되거나 저장되지 않으므로 안심하고 사용하실 수 있습니다.
- Q.'가중치 GPA'와 '단순 평균'의 차이는 무엇인가요?
- '단순 평균'은 모든 성적을 더한 뒤 과목 수로 나눈 것입니다. 반면 '가중치 GPA'는 각 과목의 성적에 '학점(Credit)'을 곱하여 계산하므로, 학점이 높은 과목일수록 최종 성적에 더 큰 영향을 미칩니다.
- Q.목표 성적 모드에서 왜 '달성 불가'라고 나오나요?
- 현재까지의 성적과 반영 비율을 바탕으로 계산했을 때, 기말고사에서 100점을 받더라도 목표하는 최종 성적에 도달할 수 없는 경우에 표시됩니다.
- Q.미국 4.0 척도에서 A+나 B- 등을 사용자 설정할 수 있나요?
- 네, 가능합니다. 기본적으로 표준 4.0 척도를 제공하지만, '성적 척도 설정'을 열어 학교 시스템에 맞게 알파벳과 숫자 값을 자유롭게 변경하거나 추가할 수 있습니다.
- Q.숫자가 낮을수록 좋은 독일 성적 척도도 계산 가능한가요?
- 네, '독일 (1-6)' 척도를 선택해 주세요. 독일 시스템에서는 1.0이 최고 등급, 6.0이 최하 등급입니다. 이 도구는 이러한 역순 척도 계산도 완벽하게 지원합니다.
- Q.계산 결과를 저장하거나 인쇄할 수 있나요?
- 개인 정보 보호를 위해 데이터를 저장하는 기능은 지원하지 않습니다. 결과를 보관하려면 스크린샷을 찍거나 메모장에 복사해 주세요.
