Do you have a plan for if you leave? I mean, do you think you will work more on getting better with computers by doing so?
What kind of job would you like? Have you considered the complications that can come from not graduating? (Less jobs available, less pay etc)
I mean, if you have a good plan, it's not school has to be in it, but if you don't, it's probably a bad move to just quit. Even if you feel like you learn nothing, which is also something you can do something about, you will get a diploma or something at the end of it, which is highly valuable at the job market
