Know how many answers there are on a test, but want to know the grades you could possibly get? Use this! I made this in my spare time. If you want the logic, here's how it works: After asking the amount of questions on the test and how many you got wrong, it subtracts your wrong answers from the total amount of questions to get how many right questions you got. Then, the calculator takes the amount of right answers and divides it by the total amount of questions. You would normally get 0 followed by a string of numbers, but the calculator multiplies it by 100 to get you your score. (So much explaining.)
