Oh man did I hate math up until algebra. It just seems like pointless memorization and rote work. Then with algebra suddenly I could see applications. "I can actually solve problems with this" and my grades went from Cs to As immediately.

I still remember the test I took in 7th grade to qualify to take algebra in 8th grade. For reasons I don't understand I was in a panic for nearly the entire test. My hands were shaking. I don't think I even finished it. Yet somehow I passed it and that was a turning point in actually starting to like math for me.
