What is the absolute best book for re-learning forgotten math for CS?

Hey,

so I was accepted to a UNI CS program.

Technology is my passion and I love learning and re-learning stuff. Last time I saw any mathematics was 3-4 years ago and since I have just a few months left before I start the curriculum so I'd like to get back on track.

What is an absolute best book for re-learning math if you already know the underlying meaning behind the concepts? (Bonus points if it's already CS-oriented)

Thanks guys
