How can i write an essay about myself in french

You have a problem. you have a job interview in town but you do not know how to get there. explain what you would do in two to three french sentences. be sure to use the conditional tense.

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?

Can somebody fully explain the “le passé composé régulier et irrégulier avec avoir” thing to me
