I hate society's obsession with academia

I'm a tutor and I teach coding lessons to kids. I teach in a project based way where kids are building practical skills that are useful to life such as building websites.

I have a great demographic of students where most of them attend private school in the uk so the parents are okay with paying good money and also value education highly.

The problem is, that whenever a student has their GCSE exams upcoming, a lot of parents cancel their coding lessons so they can focus on school exams.

I HATE school. For me, it's pointless memorisation, exam based nonsense that has no semblance of importance in the real world other than the fact we choose to give it importance. I did amazing at school myself, but I can say that all my grades and qualifications in the end are useless since I chose self employment.

Why do parents sacrifice learning actual important stuff over vain shit like school exams. Also the exams never get any less frequent so basically once they start, they'll be having important exams every 6 months until they graduate university so they're basically giving up on anything educational aside from academia
