You may want to try working through Spivak's _Calculus_ [1] textbook. It is a bit more involved than most calculus textbooks used in universities today, so it will likely not feel like you are simply repeating something that you have already done. I would recommend this book to anybody who wants to brush up on calculus after studying it before.
I have Spivak's book actually, I got the hardcover from a used book store several years ago. It did seem a bit daunting to me from what I recall, I had used Tom Apostle's book when studying calculus back then.
I'll give more time to working through Spivak, hopefully it feels more approachable this time around.
