Could someone Help me with one level in Harry Potter and the Goblet of fire?

I vaguely recall playing that game when I was 9. If there's any cauldrons, drop them on the bad guys. Shoot the bad guys with your stick if you can. Maybe you should get as far from them as you can, wait for them to follow you, then turn around and blast/charm them while they run away. If none of those work, sell this game. It was the source of many headaches and feelings of worthlessness and depression. And it didn't even make sense.
