Automatically Clicking Buttons?

I have a button (named Test) and I have the X and Y coordinates of the 3 buttons (Which are A, B and C) to click. Now what I want to do is, when the Test(button) is pressed, timer1 (22 seconds) would start and after 22 seconds it presses automatically button A and if it isn't the right button then it will wait another 22 seconds and then presses button B and if it is right it will start another 22 seconds and if it is wrong it would start another 22 seconds and press button C. If the correct button was B then another 22 seconds would start and this time it would start again from A.

1.When Button TEST is press the timer will count down 22 seconds.

2.After 22 seconds it will press the button A (timer will stop)

3.If button A was the correct letter then Timer will count another 22seconds.

4.If button A was wrong it will start the timer (22seconds) and then press B (timer stopped).

5.If button B was correct, timer will start another 22 seconds (back to step 2)

6.If button B was wrong then timer will start and will click button C. (timer stopped)

7.If button C was correct then timer will start (Back to step 2)

8.Will continue like this until 25 clicks had been made then it will stop.
