When I was in Grade 10, my math was NOT good (thanks to a crummy teacher in Grade 9, "Jolly Wally" ).

My math teacher offered to tutor me twice a week. I felt ashamed at first - but the patient one-on-one really helped. I saw my grades go from 60's to 80s and even a 90 once - and in GEOMETRY!

A couple extra hours a week can make a difference. It would be pro-active of you to try this.

Just a thought.
