job during high school?

I'm in 11th grade and i really wanna pass this year but at the same time i need money and experience, and one of the only valid jobs in my country for my age is a part time job, 6 days weekly and 8 hours a day... so if i go to school from 8am to 1pm and my shift starts at 5pm and ends 12:30/1am, which means i have four hours to eat, poop and study and 6 hours of sleep... so should i go for it or just focus on my studies?
