hi,

Im getting an error on the case lines in Red:
========================================
Cannot implicitly convert type 'bool' to 'int'
========================================
Any help please. Thanks

Code:
 switch (total)
            {     case (total < 50):                    
                   grade = "FAIL";

                case (total >= 50 && total < 70):                
                  grade = "PASS";

                    case (total > 70 && total < 80):
                    grade = "MERIT";

                   case  (total >= 80 && total < 90):        
                   grade = "DISTINCTION";
