You can save save all the questions in a string variable here is an example of a variable with 3 questions "1+1 ; 2+2 ; 3+3" after that when you start your game you can set what question to show like: set text -> tokenat(variable,0,";") this will show the question 1 etc.
Also you can kinda fix your code , lets say you check if Wrong >= 1 Wrongco set invincible , you do it too much times , but you only need to add it in one event.
Also you have the if Wrong => 1 and if seed is visible / if Wrong => 1 and if seed2 is visible / seed3 , seed4.
You can add as event the if wrong => 1 and the other as subevents.
