I'm looking to create an app that is similiar to [login to view URL], but I can change the problems and answers. So here's the main idea:
The user can select a topic from the home page (I want to be able to add and delete topics whenever I want. Topics such as "Slope Intercept Form, Pythagorean Theorem, etc.) When they select a topic, a question comes up from that topic. The question will be either words (text) or a picture (pdf/jpeg). Below the question is a text box for the student to put their answer. Below the text box is a button that says "Submit" Once they type in their answer and hit "submit", If the students answer from their text box matches my pre-set answer, then they advance to question 2. If their answer does not match my pre-set answer, then a picture (pdf/jpeg) of my explanation on how to actually do the problem correctly is displayed, and below the explanation picture is a button that says "Got it". Once they click the "Got it" button, they advance to question 2.
I want to add or delete as many questions as I seem fit also.
