Spaced repetition is good for learning, but you need to be using it all along. You are basically “reviewing” the material, like for an exam, but in smaller doses, continuously. It does not help you cram if you haven’t been keeping up. The “spaced” part is based on refreshing your knowledge just as it is fading from the previous repetition. As time and repetitions pass, the repetitions can get farther apart, because it is increasingly “fixed” in your memory.
