Test figures are too small - I can't read them!
The test figures embedded within the tests are sometimes hard to read and they don't have a "zoom" feature within the test.
There's a workaround though - "right click" on the image and Open in new tab. The image will load in a new tab, often larger than displayed in the quiz. You can also use the Ctrl/Cmd +/- keys to zoom in and out of the image.
