Attendre – does not mean “to attend.” Don’t even think it. Also, note that in English you wait “for” someone, but you do not add “pour” to the corresponding French phrase. “J’attends mon ami.”
Entendre = to hear. Écouter = to listen. These are not the same verb!
Prétendre – does not mean to “pretend.” It means to “claim” as in: “He claims that he’ll be on time.” (Which will make “attendre” unnecessary.)
Obéir à – in French, you do not “obey someone” you “obey to someone” (or something). “J’obéis à la prof mais tu n’obéis pas à la prof.”
Réussir – it is always important to study how a verb is used in context and “réussir” is a perfect example of this. When you pass a test “vous réussissez à un examen.” If you manage to do something “vous réussissez à le faire.” However, for many things, you can use the verb without any extra little words added in. For example:
“She makes good cakes.” – “Elle réussit bien les gateaux.”
“He’s making a success of his life.” – “Il réussit sa vie.”
