A test score calculator converts the number of questions you got right out of the total into a percentage and a letter grade. Enter how many you answered correctly, or switch to entering how many you got wrong and it works out the rest. If wrong answers carry a penalty — some standardized exams deduct a fraction of a point to discourage guessing — set the points lost per wrong answer under advanced options; otherwise every wrong or blank question simply scores zero.
Worked example: 18 correct out of 20 is 18 ÷ 20 × 100 = 90%, an A-. If instead a quarter-point penalty applied to the 2 wrong answers, the raw score would be 18 − 0.25×2 = 17.5, giving 17.5 ÷ 20 = 87.5%, a B+.
A reference table shows exactly where each percentage falls on the letter scale. Teachers use it to grade quizzes and set curves, and students use it to check a score before results are posted or to see how many more questions they need right to reach the next grade.
Mafunso ofunsidwa nthawi zambiri
Kodi ndingatani kuti ndiwerengere peresenti yoyeserera?
Kugawa mnda wa mayankho oyenera ndi mnda wa mafunso ndi kuwonjezeka ndi 100. 18 oyenera kuchokera 20 ndi 18 ÷ 20 × 100 = 90%.
Kodi ndingapeze bwanji akaunti ya banki?
Yes — set the mode to “Number wrong” and type how many you missed. The calculator subtracts that from the total to find how many you got right, then works out the percentage way.
Kodi kodi chindapusa cholakwika cha yankho chimagwira ntchito?
Some exams subtract a fraction of a point for each wrong answer to discourage guessing. If you set a penalty, it is multiplied by the number of wrong answers and removed from your raw score before the percentage is worked out.
Kodi mafunso anga angatani kuti ndizichita zoipa ndipo ndipite?
Divide the passing percentage you need by 100 and multiply by the total to get the minimum correct answers, then subtract from the total. To keep a 70% pass on a 20-question test you need 14 right, so you can miss at most 6.
Kodi ndiyenera kuchita chiyani kuti ndikhale ndi A?
Pa mfundo yofala A imayamba pa 90%. M’mafunso 50, mufunika 45 oyenera kuti mulandire A, 40 kuti mulandire B ndi 35 kuti mulandire C. Muyenera kuwonjezera 0.90 ndi mfundo zoposa 50 kuti mulandire A.
Kodi yankho lopanda mawu limawerengedwa ngati lopanda tanthauzo?
Mwa default yes — aliyense funso si anayankha bwino amapeza zero, kotero zosawerengeka ndi zoyankha zoipa mtengo monga. Iwo okha kusiyana ngati inu kuika zoipa-kuyankha chilango, amene amagwiritsa ntchito kwa idadi ya zoyankha zoipa.
