Replying to Where to watch F1?

I know there's only one more race this season. I have cable and speed channel (the only channel that broadcasts the races) costs so much extra every month, which I can't afford. So I haven't been able to watch any of the races this year. I've just been going online and checking the points to keep myself updated. I just wondered if there was a site online that I could watch live F1 races on. I know the amount of followers of F1 on newschoolers is pretty slim but I can't find anything. Just wondered if anyone knows. Thanks guys.
