Add an option to display the question then after a set amount of time defined in preferences highlight the correct answer. A second programmed timer to move onto the next question. Repeat through each question. If the “Explain” option is used, then pause the timers until manual movement to next question. This does two things, It helps with reinforcing the questions and answers and also paces the timing. This is the same as pressing the “I don’t know link” but on a timer instead of a press.
