SAT is tomorrow morning haven't prepared at all, help?

So I forgot I had to take the SAT tomorrow morning. I have not studied at all for any of it. Should I still do what all the sites say about not studying? I know that cramming won't do anything but is there a site that gives you tips about taking the SAT like every simple math start with answer C because its the middle value of the answers, and then go higher or lower from there? Little tips like that. Thanks. Oh and for next time, what should I do to study, because obviously I'm not going to do to great on this one. Anything online would be preferable but books work too, and iPod touch apps work too! Thanks.
