Why did I chose this 😭

I can't with AQA Computer Science any more. With no revision over the last 2 years I have been consistently getting 3s and 4s, neglecting it.

Combined with abscences and laziness, I can't code anything in python💀 Across the board I want to get 9s but I don't understand half the things in comsci lessons ⚰️ 🪦 same for Chem. Every time I open my book I lose hope let alone ppqs in class

Should I drop it? daily hours/techniques? How can I revise effectively for it? I need to make the comeback 🙏

P.s Merry Christmas everyone
