WJEC A Level Computer Science is Stressing me out

Well,
this past week, I haven't done any work at all. Which is the thing that's stressing me out right now?
It's a joke though. The coursework is 20% of the whole of the A level. Even though it is 20%, WJEC expects us to do more than 100 hours of work for this 20%. Which in my opinion is stupid.
To my understanding, I think they should push that to at least to 45% or decrease the amount of coursework you have to do!
When practicing exam questions for the upcoming exam which I will be doing in June, the stress levels increase.
In my head, I'm always thinking what's the point of doing the coursework when I can easily smash the paper.
But then I'm scared of what the teacher of mine will tell my parents of how careless and lazy am for not doing the coursework as that's all on me.
I just wanna speak to someone, who is in the same situation as me. Everyone could say just put the time in the coursework once and for all and finish it.
But then how am I meant to invest, time on the other 2 A levels of mine.
I've never felt so pressurized as I am right now.
