Would someone me with this ? ? you!

Any french speakers? i need some . how would i say 'my oldest brother is very tall, interesting, and good at drawinng.' in french? would it be: mon (i don't know the french word for oldest) frère est très grand, intéressant, et bon à dessin. also, how would i say 'my dad is good at his work' in french?

When you take french in high school, would you already have to have learned french or no?

Fill in the blank with the appropriate past-tense form of the verb "se coucher". elle s'est couché s'a couché s'a couchée s'est couché
