I'm a 9th grade student (14 years old) who is described as an "intelligent person", at least relative to my peers. My parents are divorced. I live with my younger brother and mother, while my father lives and works in another country. I'm into programming (I want to become a software dev, and I already have a small part-time job online with some friends), watching anime, playing games etc.
There's one issue though: At school, I don't really get excellent grades, or the first in terms of scores, even though I have the ability to. I also don't revise at home, or do my homework as it should be done, except in Maths, partly because I do most of it in class.
My parents have told me many times that I should get the best/perfect scores, and think that while at home I should study all week except for a 2-hour break per weekend. I have no computer or phone except for those 2 hours. I am not convinced that they are correct.
I have been since getting worse scores since my access has been limited so severely. I tried suggesting a flexible timetable to study and use electronic devices in a balanced way, but that got rejected by my father. I was later asked to choose between being an excellent student (the restriction would apply) or be a mediocre one (in my father's words, that then he would give me back the computer/phone). I chose no option initially, because I want the best of both worlds, but he insisted, so I finally chose the second option. Then right after that he talked to my mother and told her to take away everything from me (including tearing my debit card apart), that's when he truly deceived me.
Perfection isn't everything; even if I am not the first in my class, I get one of the best grades (18/20 in the overall yearly score.
Recently a trip was announced to a country by our school but my father gave me the choice again, but this time I chose the first choice (only way to go to the trip), but that's it, only a choice, I haven't picked up a single book yet. He also told me that as long as I don't abide by anything, then they too won't, and I will have an indefinite restriction on everything else.
How can I convince them that top grades aren't my priority, but at the same time keep my privileges as an incentive to achieve them?
