Cloze creation tool
To create cloze-deletion (fill in the blank) exercises, put the terms you want to replace (separated by spaces) in the left box and the text that you want to use in the right box. Clicking "Create Exercise" will make an "exercise" version of the text, with your terms replaced by either spaces or numbers, and a solution on the right. The "Language" chooser just gives you some examples to work with: you can use terms and text in any language, and edit both boxes however you like to create new exercises.
