Rav Nahman has in one Torah lesson the idea that when one finds that he learns but does not understand the advice is to shout the words. On occasion I have tried that myself and it works, but it seems to be advice for occasions that present the opportunity to do so. Because in general, I find it simpler to take the basic path of learning of Rav Nahman of just saying the words and going on more practical.
Also Rav Nahman did bring the idea of review both in the LeM and Sefer HaMidot. But clearly according to the Conversations of Rav Nahman 76, that is only a part time affair. Still I want to bring one way of review that I have tried and seems to work for me. As I progress through a book, I go one page forward and then keep my place and then review all the way back to the beginning. Then I go one more page forward and then from that new place also review back to the beginning.
[But I should add that there were different ideas of how to learn in depth in Shar Yashuv in NY and the Mir in NY. But in any case, the emphasis of the Litvak world was to learn in depth along the lines of Rav Haim of Brisk and Rav Shach. [That is a more global approach than the previous achronim later authorities [like the Pnei Yehoshua and Maharsha] that concentrate more on local issues.]
