The link above is my filling-gap exercise. I hope you can take a moment of your busy life to check it out. In my opinion using Hot Potatoes is easier than Microsoft Excel in creating new exercises. Hot Potatoes only requires you to click certain boxes and your exercise will be done in no time. However, Excel is quite complicated when you have to write certain formulas and a tiny mistake will cause you the greatest impediment to your progress.
