That is the beauty of this book, there is no need for any extra resources. Install SICP package in Dr. Racket [1] and start reading the book. Try your best to solve the exercises, and don't give up easily on the exercises. Thinking over the exercises and solving them is the best way to assimilate learning from SICP. I read only the first 3 chapters, and relied on notes from Eli Bendersky [2] to check when stuck with exercises.
