Question

Rentres-tu à la maison pour (for) étudier (USE YOUR IN FAMILIAR WAY) cours de philosphie?

Would it be TES OR TON to fill in the parntheses

Answer 1

It depends. You can say both, for example :

"Tes" if it's a school, with many students and you wasn't the only student in the class when the course happened

"Ton" for example if this is a personal philosophy course (or a piano course) you can say "ton"

But in your example, i guess it would be better to say "tes"
