What should I do to get a good foundation for Methods 3/4?

[swampman]

I have a really weak basic knowledge for Methods 3/4, so I was wondering if there was any good resources for self- studying over the holidays? (PDF links or sites would be great)

Thanks!

http://www.purplemath.com/modules/index.htm is pretty good for some of the more algebra stuff - pretty important to be on top of most of this assumed knowledge type stuff here.
khanacademy.org has some decent videos for a lot of things, just depends if his style is your thing or not
MIT OpenCourseWare / the highlights for highschool might help with a few topics, but a lot of stuff there assumes knowledge beyond methods, so probably isn't too much help for you atm

Not everything on those sites is relevant to methods, though.

Otherwise just taking a look at questions, taking it topic by topic and breaking everything down into small concepts might help. You'll want to keep an eye out for when you're struggling or not completely understanding something too and just focus on those little things. The internet is generally a good resource, it's just requires you to sifting through things quickly to find what you need.
