Not a popular opinion (for some reason), but you take notes for a reason. It's worth pulling out your course notes (even if from a year ago) and read through them. This will not only refresh the material, but also pull back memories of class. I'd use this as a starting point. From there, it should be obvious what your weak points are (i.e. is it everything? only static friction concepts? etc.). Then, a basic review book should give the rest of what you "need." YouTube videos are, as mentioned above, an excellent free source.
It's sad that most of us do not remember much, if not any, of what we learn in undergraduate studies. I still have my college notes around (mainly because I'm a pack-rat...they're about a decade old at this point...) and will peruse them from time-to-time out of boredom and sometimes if I'm really curious and don't feel like googling.
