I get so frustrated when I try typing a long equation into the text box, only to find out that once I hit the submit button, it’s incorrect. Usually, when I see the solution, I realize that my mistake was just a typo. This is why I am here requesting to get a “Second Chance” feature. If you click “check” and your answer is wrong, a pop up will appear saying you got it wrong, but you can attempt to do this a second time. If you do get it wrong the second time, you will have to do an extra question with a similar concept to the one you got wrong. Maybe, you can only have a certain amount of second chances for each practice you do. For example, you may only use the “second chance” feature two times out of the four questions. I think learning should be something that you are looking forward to rather than despising having to type and retype long equations. I hope that this feature is considered and looked at.
