To create a multiple choice album in the Words Education app, you will need to create an image file for each question, with letter answers (A, B, C, etc.). E.g., a question might look like this:
There's a number of ways to create an image out of that text. Please search for "text to image" with your favorite search engine.
To add an answer key to an image, hover your cursor over the image you would like to edit and click 'Edit'. Once you are on the Edit Image page, add the answer letter in the 'Add word' text field, e.g. 'A', 'B' or 'C'.
You can find examples of multiple choice albums in the myOsmo custom album collection (search for "MultipleChoice") and make similar images for your own albums.
Find more information about custom albums in our PDF guide to the Words Education app.
