Can I cope during year 12?

Okay I’m getting very stressed as I have so much on at the moment and need advice on whether to quit something so at the moment I’m taking A levels in Maths Psychology and history where I’m aiming for A*AA and I’m also doing extra study as I’m planning on applying to Oxford so can I cope with these extra things

9.5 hours working each week
Driving lessons (1 hour each week)
workouts gym (1 hour a day)

As well as parties and seeing grandparents at the weekend
I NEED TIME MANAGEMENT HELP and I need to know what my next step should be😂😂
