using points tracker on video - like UK driving hazard perception test

I am a total beginner and want to make a simple game, just like the UK driving hazard perception test. I need the user to earn points by clicking during the correct times of an educational video. That's it!

What tutorials do I need to get started?

More detail: "If you click the mouse while in the first segment (i.e. just has the potential hazard starts to materialise) you will obtain the maximum score of 5 points. If you click in the second segment of this window of time you will score 4 points, then 3, then 2 and then in the last segment just 1. If you don't click the mouse in this window of time you will score nothing in respect to that hazard. Within the scoring window if you click several times only the first click will be used to determine your score (i.e. the highest scoring click)."
