one of my parents (dad, its always the dads) is interested in my education to the extent where he'll ask me how's school going every once in a while. I have found that, as I've gotten older, he's been less and less involved in my academic life which I'm grateful for, actually. He's not disinterested per se, just would never actually tell me do work or whatever, because he kinda knows I'm capable of doing well. I hate being told to do work so its good that I'm not constantly nagged like some of my friends.
I remember the days where I'd only do work when my dad told me to (year 8/9/10..11 even), but not like some parents who stand over their children at their desks with whips and **** lol. I know a guy whose mum marks his past papers...hes in year 13. I dont even think my mum knows what a past paper is lol. All of my friends whose parents (including Past Paper Mom)are super pushy in the academic sense tend to be the ones who dont do well. I mean, your parents are going to be doing your degree for you; the hardest part for some people will be trying to muster together the motivation unless you're taking your parents with you to Uni or something lol.
All in all, parents have intervened less and less in my academic life as I've gotten older. I'm very happy about this as its encouraged me to take the initiative in my life and develop a sense of independence.
