I agree with Ramsey Musallam when he talked about rule number three: practice reflection for the following three reasons. Firstly, reflecting what you did is important, making sure what should you not do next time or pay more attention to some stuff. Secondly, if you review what you have learned, you might exend your knowledge by using the imformation you just got. Lastly, reflecting makes the imformation harder to forget, because you made a good impression of it.
Due to these reasons, I think the reviewing what you have just learn is important.
