Make a quiz matrix scoring system

I have a quiz with 21 questions divided into two parts, questions 1-13 and questions 14-21. There are five possible answers, with the first three not important so I assigned them a value of zero. Now, however, I have three rules for calculating the final three options. In the program in which I have to do the quiz, I have general arithmetic operations available; addition, subtraction, division, multiplication and use of parentheses. I need to put together a formula that would give me different ranges from which to assess which option belongs to the user who completed the quiz. The rules are: OPTION 1 = if questions 1 - 13 have six or more answers with 3 or 4 and questions 14 - 21 if there are six or more answers with 3 or 4 OPTION 2 = if questions 1 - 13 have six or more answers with 3 or 4 and questions 14 - 21 if there are less than six answers with 3 or 4 OPTION 3 = if there are less than 5 answers in each set of questions with 3 or 4 It would be easiest if I could set ranges, for example: 0 - 10 = OPTION 1, 11 - 20 = OPTION 2 and 21 - 30 = OPTION 3 Thanks for any help!
