Not really lovin possesive pronouns

So I just got my English test back.. I got an 84% on possessive pronouns. Not so thrilled. It's enough it doesn't hurt my need to not take that final but I think I coulda done better if I hadn't put it off for a month cuz I didn't like the new teacher guy. He's mellowed out tho.. and so have I.. so it's.. tolerable... yeah anyway that's my update.. next stop pronouns and antecedents
