        grade=Integer.parseInt(g);
        
        switch(cat){
            case 1: 
               
                 JOptionPane.showMessageDialog(null,"Prefect score");
            break;
            
            case 2:
             
                JOptionPane.showMessageDialog(null,"well done");
            break;
       
            case 3:
               
                JOptionPane.showMessageDialog(null,"Above the averageg");
                break;
             
            case 4:
                
                JOptionPane.showMessageDialog(null,"Average");
                break;
                
            case 5:
              
                JOptionPane.showMessageDialog(null,"Below the average... Shame on you");
                break;
                
            
            
        }

Remember that instructions are executed in the order you see them. If you put instruction B before instruction A, chances are it'll be run first.

With this in mind, can you figure out why the following code is in the wrong place?

        cat= grade/10;
