harry potter and the philosopher`s stone (ps1) (devil`s snare)

could someone give me some hints on how to get past the devil`s snare

Old game! I beat it ages ago! In any case, I'm assuming you're from england because it's "Philosopher's" not "Sorcerer's." In any case, I can't remember enough to help you out, but you can go here:
www.gamefaqs.com
They've got free guides for practically every game in existence!
Go here (http://gamefaqs.com/console/psx/) for the ps1 section, then just click "H" at the top and find your game.

ok thanks i will try it out.

when the snare thingy's vines come at you use Incendio on them. that should remove them from you. then use incendio on the main tree or on where Ron and Hermy is stuck....
