It would be much easier to get through the courses if the web page support the keyboard for every test. Instead, some tests allow you to type a number to match the word while others require that you click with the mouse. Please add full support for keyboard only progression through the tests.
Agreed. Seems like it should be an easy fix. Also, it would be nice to minimize the need to go back and forth between typing Korean and English in a particular exercise, possibly just requiring one change midway. Ideal would be doubling the number of exercises and having the same set of exercises in both languages.
