Hey Lilybiri,
Sorry for not answering all your questions in my previous post!
Theme (responsive): "White" - The colors of the master slide are adjusted to suit the design I am intending to use.
Buttons: All other buttons - except for "Submit" - are deactivated because all question slides are time-driven. Students will have to answer the questions within the time limit specified. Otherwise, they will be automatically directed to another question once the timer finishes counting down.
