Create a variable to keep track of the number of questions answered.

Each time a question is answered increase the variable by 1. Then check to see if the variable equals 25 (or the number of questions in the test if the number of questions can vary).

After increasing the variable by 1 create the following blocks:

If questions answered = number of questions in test
Then go to results screen
Else go to next question
